Description

Technical Field

[0002] During the manufacturing process, metal parts often develop various defects, such as cracks, missing parts, excess parts, bumps, and scratches, due to factors such as materials, processes, and equipment. These defects seriously affect the quality and performance of metal parts and may even lead to safety accidents. Traditional methods for detecting metal defects rely primarily on manual visual inspection. However, manual inspection is slow, difficult to meet the needs of large-scale production, and is susceptible to subjective factors, making it difficult to ensure the consistency and reliability of test results. Furthermore, prolonged visual inspections place a heavy strain on workers' eyesight and physical strength.

[0003] With the development of computer vision technology, automated visual inspection equipment has gradually become the mainstream technology for metal part defect detection. These devices capture metal part images with high-resolution cameras and then use image processing algorithms to identify and classify defects.

[0036] Example 1

[0037] Reference Figure 1 and Figure 6 , as a first embodiment of the present invention, provides a defect detection device, comprising,

[0038] The conveying path 100 is provided with two groups, and the conveying path 100 includes an annular segment 101. The openings of the two groups of annular segments 101 face in opposite directions. The conveying path 100 is used to drive the inspected parts to move; the flip assembly 200 is located between the two groups of conveying paths 100.

[0039] The device also includes a scanning component 300, which includes a scanning camera, which is also provided in two groups. Each scanning component 300 corresponds to a conveying channel 100. The scanning component 300 is located on the opening side of the conveying channel 100. The position of the scanning component 300 is higher than the position of the conveying channel 100. The shooting range of the scanning component 300 covers the annular segment 101. The scanning range of the scanning component 300 is larger than the range where the annular part is located.

[0040] The conveyor belt 100 also includes a straight section 102. Straight sections 102 are provided at both ends of each group of annular sections 101. The distance between each scanning component 300 and two adjacent straight sections 102 on the same conveyor belt 100 is the same. From the top view of the device, the scanning component 300 is not located on the inner side of the annular section 101. The scanning component 300 is located on the middle line between the two straight sections 102 and away from the center point of the annular section 101. This setting is to enable the scanning component 300 to completely cover the annular section 101.

[0041] For the conveyor belt 100, the travel path of the part to be inspected is from the straight section 102 to the annular section 101 and then to the straight section 102. The part to be inspected is conveyed one by one to the flipping assembly 200. In this device, the part to be inspected moves on one of the conveyor belts 100 and is scanned by the scanning assembly 300 corresponding to the conveyor belt 100. Then the part to be inspected is transported from one conveyor belt 100 to the flipping assembly 200. The flipping assembly 200 can flip the part to be inspected, and then place the part to be inspected on another conveyor belt 100, and then be scanned and inspected by another inspection component. This inspection process is to completely scan multiple surfaces of the part to be inspected.

[0042] Reference Figure 6 In this embodiment, the part to be inspected is a slider-type metal part. All six outer surfaces of the slider-type metal part need to be inspected. The part to be inspected first moves on one of the conveying lanes 100. When the slider-type metal part moves on the vertical lane and the circular lane, the front side, rear side, top side and side close to the scanning component 300 of the slider-type metal part can all be scanned; the flipping component 200 can flip the slider-type metal part upside down so that the top and bottom surfaces of the metal part are interchanged, and the slider-type metal part is placed on the next conveying lane 100. When the slider-type metal part moves on the next conveying lane 100, the corresponding scanning component 300 can scan the other side and bottom surfaces of the slider-type metal part that have not been scanned before, so that the scanning of the six surfaces of the slider-type metal part can be realized.

[0043] The device can scan a variety of metal parts that require scanning multiple surfaces, and can effectively adapt to metal parts of different shapes. In addition, the device only has two sets of scanning components 300 to achieve multi-faceted scanning of metal parts.

[0044] Example 2

[0045] Reference Figures 1 and 2 and Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the flip assembly 200 includes a bracket 201, a motor 202 fixedly placed on the bracket 201, a transmission member 203 connected to the output end of the motor 202, a flip member 204 connected to the transmission member 203, and a support member 205 connected between the flip member 204 and the bracket 201. The motor 202 drives the transmission member 203 to move, and the transmission member 203 drives the flip member 204 to flip, and the support member 205 provides support for the flip member 204.

[0046] Reference Figure 6 The position of the first detected piece is higher than the conveying lane 100 of the second detected piece, and the height of the flipping piece 204 is between the two conveying lanes 100.

[0047] In summary, the inspected piece falls from the previous conveying lane 100 onto the flipping piece, the flipping piece catches the inspected piece, the motor 202 drives the flipping piece to rotate through the transmission piece 203, thereby driving the inspected piece to flip synchronously, and finally falls onto another conveying lane 100.

[0048] It should be noted that the flipping assembly in this embodiment can cause the inspected piece to flip back and forth in a somersault-like manner along the end extension direction of the conveyor belt 100, so the two conveyor belts 100 are distributed in a serpentine shape as a whole. This arrangement is to enable the other side of the inspected piece to be inspected to be inspected; if the flipping assembly can cause the inspected piece to flip left and right along the end extension direction of the conveyor belt 100, the two conveyor belts 100 can be arranged in a runway shape, which can also enable the other side of the inspected piece to be inspected to be inspected.

[0049] The remaining structures are the same as those of Example 1.

[0050] Example 3

[0051] Reference Figures 2 to 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the bracket 201 includes a base 201a, two side-by-side vertical frames 201b fixedly installed on the side of the base 201a, and a crossbeam 201c fixedly installed between the two vertical frames 201b, and the motor 202 is placed on the base 201a.

[0052] The flip member 204 includes a flip block 204a, an accommodating groove 204b is provided on the inner side of the flip block 204a, the flip block 204a is open, and a notch 204c connected to the accommodating groove 204b is provided on the upper side of the flip block 204a. The notch 204c is used to facilitate the entry of the detected part into the accommodating groove 204b. A sleeve 204d is fixedly connected to the side of the flip block 204a away from its open end, and a rotating shaft 204e is fixedly sleeved on the inner side of the sleeve 204d. The support member 205 and the transmission member 203 are both connected to the rotating shaft 204e. The support member 205 provides support for the rotating shaft 204e. The transmission shaft can drive the rotating shaft 204e to rotate, thereby driving the flip block 204a to flip around the rotating shaft 204e.

[0053] The support member 205 includes a fixed block 205a that is rotatably sleeved on the outside of the rotating shaft 204e. Fixed rods 205b are connected to both sides of the fixed block 205a. The end of the fixed rod 205b away from the fixed block 205a is fixedly connected to a fixed seat 205c. The fixed seat 205c is fixedly installed on the side of the stand 201b by bolts. The fixed block 205a can provide support for the rotating shaft 204e.

[0054] The transmission member 203 includes a fixed pin 203a arranged on the side of the beam 201c, and the fixed pin 203a is rotatably connected to a transmission frame 203b with a hollow inner side; the end of the rotating shaft 204e away from the flip block 204a is fixedly connected to a transmission block 1 203c, and the side of the end of the transmission block 1 203c away from the rotating shaft 204e is fixedly connected to a transmission column 1 203d. The rotation of the transmission column 1 203d can drive the transmission block 1 203c, the rotating shaft 204e and the flip block 204a to rotate synchronously, and the transmission block 1 203c and the flip block 204a are in opposite directions.

[0055] The output end of the motor 202 is fixedly connected to the connecting shaft 203e, the end of the connecting shaft 203e away from the motor 202 is fixedly connected to the transmission block 203f, and the side of the transmission block 203f away from the connecting shaft 203e is fixedly connected to the transmission column 203g.

[0056] A connecting block 203h is movably connected to the connecting shaft 203e. Connecting rods 203i are provided on both sides of the connecting block 203h. The connecting rods 203i are fixedly connected to the stand 201b.

[0057] Reference Figure 2 and Figure 3Furthermore, the transmission column 1 203d and the transmission column 2 203g are both movably connected to the inner side of the transmission frame 203b. The length of the transmission block 203f is greater than the length of the transmission block 1 203c. When the motor 202 rotates, the motor 202 can drive the connecting shaft 203e to rotate synchronously, thereby driving the transmission column 2 203g to rotate around the motor 202 through the transmission block 203f. The motor 202 rotates counterclockwise, and the transmission frame 203b is driven to swing counterclockwise around the fixed pin 203a through the transmission column 203g, thereby driving the transmission column 1 203d to rotate counterclockwise, and the flip block 204a is caused to rotate around the rotation axis 204e through the transmission column 1 203d. When the transmission column 203g moves to a certain critical position on the right side, the transmission column 203g leaves the right inner wall of the transmission frame 203b and continues to move to the left inner wall of the transmission frame 203b, thereby driving the transmission frame 203b to rotate clockwise, thereby driving the transmission column 1 203d to rotate clockwise through the transmission frame 203b, thereby causing the rotating shaft 204e to rotate clockwise, driving the flip block 204a to flip back to its original position; the motor 202 drives the transmission block 203f to rotate one circle, and the flip block 204a rotates half a circle counterclockwise and then half a circle clockwise to return to its original position. The motor 202 keeps working to enable the flip block 204a to perform periodic flipping motion.

[0058] Reference Figure 2 , is the initial state of the device. The end of the flip block 204a away from the rotation axis 204e is higher than the height of the rotation axis 204e. The open end of the flip block 204a faces the conveying path 100 that first conveys the inspected piece. The inspected piece falls into the receiving groove 204b. The notch 204c on the flip block 204a is located at the lower side of the end of the conveying path 100 that first conveys the inspected piece. The inspected piece can fall directly into the receiving groove 204b through the notch 204c because the flip block 204a Due to the tilt setting, the inspected piece can automatically slide to the inner wall of the receiving groove 204b close to the rotating shaft 204e and contact the inner wall. A fixed distance is maintained between all inspected pieces, so that the inspected pieces can fall into the receiving groove 204b when falling. The flip block 204a rotates counterclockwise around the rotating shaft 204e to turn the inspected piece over. When the flip block 204a rotates to the upper side of the end of another conveying lane 100, it can fall onto the other conveying lane 100 and continue to be conveyed.
