[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will provide a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0027] Embodiment 1

[0028] Referring to Figures 1-3 , which is the first embodiment of the present utility model, a eddy current flaw detection device is provided. Such an eddy current flaw detection device includes a base plate 1. A conveyor line 2 is provided on the top of the base plate 1. A number of follow-up toolings 3 are provided on the conveyor line 2. A metal part 4 is provided on the follow-up tooling 3. A flaw detection and inspection component 5 is provided on the top of the base plate 1. A loading component 6 is provided on one side of the conveyor line 2. A rejection component 7 is provided on one side of the flaw detection and inspection component 5. An unloading component 8 is provided on the other side of the conveyor line 2;

[0029] The loading component 6 includes an inclined plate 61. A support frame 62 is provided at the bottom of the inclined plate 61. A loading channel 63 is provided at the top of the inclined plate 61. A limit baffle 64 is provided inside the loading channel 63. Square through-holes 65 are symmetrically opened at one end of the loading channel 63. A rolling channel 66 is provided at one end of the loading channel 63. The other end of the rolling channel 66 is arranged corresponding to the follow-up tooling 3 directly below. The bottom of the rolling channel 66 is connected to the support frame 62. A baffle 67 is provided at one end of the rolling channel 66. Guide chutes 68 are symmetrically opened at the other end of the rolling channel 66. The guide chutes 68 communicate with the square through-holes 65. A lifting structure 69 is provided on the support frame 62. By placing a batch of metal parts 4 side by side in the loading channel 63, the metal parts 4 are limited by the limit baffle 64, and only one metal part 4 can pass through each time. Then, the metal part 4 is lifted onto the rolling channel 66 by the lifting structure 69, and the metal part 4 falls onto the follow-up tooling 3 through the rolling channel 66, thus completing the loading operation, eliminating the need for continuous manual loading and greatly reducing the manual workload.

[0030] The lifting structure 69 includes a U-shaped plate 691. The U-shaped plate 691 is arranged on the support frame 62. A first cylinder 692 is provided at the bottom of the U-shaped plate 691. A top head 693 is provided at the output end of the first cylinder 692. A lifting plate 694 is arranged inside the guiding chute 68. An installation groove 695 is formed at the bottom of the lifting plate 694. The top head 693 is arranged inside the installation groove 695. The first cylinder 692 drives the top head 693 to push the lifting plate 694 upward. The lifting plate 694 moves upward along the guiding chute 68. The lifting plate 694 pushes the metal part 4 upward to the rolling channel 66. The first cylinder 692 is used to lift the metal part 4, facilitating the subsequent feeding operation.

[0031] During use, the staff places a batch of metal parts 4 side by side in the feeding channel 63. The metal parts 4 are limited by the limiting baffle 64, and only one metal part 4 can pass through each time. Then, the first cylinder 692 is started. The first cylinder 692 drives the top head 693 to push the lifting plate 694 upward. The lifting plate 694 moves upward along the guiding chute 68. The lifting plate 694 pushes the metal part 4 upward to the rolling channel 66. The metal part 4 passes through the rolling channel 66 and then falls onto the follower tooling 3. Since the movement of the conveyor line 2 is in a stepping mode, the feeding operation is completed. There is no need for continuous manual feeding, which greatly reduces the workload of the staff and avoids misoperation due to fatigue, being conducive to stable and continuous operation.

[0032] Embodiment 2

[0033] Refer to Figures 1-4 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the rejection component 7 includes an L-shaped block 71. An L-shaped block 71 is arranged at one end of the conveyor line 2. A second cylinder 72 is arranged on one side of the L-shaped block 71. A rejection head 73 is arranged at the output end of the second cylinder 72. The second cylinder 72 drives the rejection head 73 to move. The rejection head 73 pushes the defective metal parts 4 away, eliminating the need for subsequent manual classification by the staff and saving a large amount of time.

[0034] A second fixing plate 77 is arranged at the other end of the conveyor line 2. A rejection channel 74 is arranged on one side of the second fixing plate 77. A limiting plate 75 is arranged at the top of the rejection channel 74. A first fixing plate 76 is arranged between the rejection channel 74 and the bottom plate 1. The defective metal parts 4 are guided and collected through the rejection channel 74, facilitating subsequent processing.

[0035] During the use process, after the metal part 4 drops onto the follower tooling 3, the follower tooling 3 moves along with the conveyor line 2. After the metal part 4 moves to directly below the flaw detection component 5, the conveyor line 2 will pause, and the flaw detection component 5 is used to perform flaw detection on the metal part 4. If a defect is detected in the metal part 4, after the conveyor line 2 starts, the defective metal part 4 moves to the rejection component 7. The second cylinder 72 is started, and the second cylinder 72 drives the rejection head 73 to move. The rejection head 73 pushes the metal part 4 into the rejection channel 74. The metal part 4 can slide down along the rejection channel 74 through the limit plate 75 and then be collected and processed, eliminating the need for subsequent manual classification by workers. This not only saves a large amount of time but also improves work efficiency.

[0036] The remaining structure is the same as that of Embodiment 1.

[0037] Embodiment 3

[0038] Referring to Figures 1-5 , this is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that the blanking component 8 includes an L-shaped plate 81. The L-shaped plates 81 are symmetrically arranged on the top of the bottom plate 1. An installation bottom plate one 82 is arranged on one side of the L-shaped plate 81. An electric cylinder one 83 is arranged on one side of the installation bottom plate one 82. A slide table one 84 is arranged on one side of the electric cylinder one 83. An installation bottom plate two 85 is arranged on one side of the slide table one 84. An electric cylinder two 86 is arranged on one side of the installation bottom plate two 85. An installation block 87 is arranged on one side of the electric cylinder two 86. The clamping cylinder 810 can be driven to move along the horizontal and vertical directions through the electric cylinder one 83 and the electric cylinder two 86, facilitating the blanking operation.

[0039] A transverse plate 88 is arranged on one side of the installation block 87. A connecting block 89 is arranged between the installation block 87 and the transverse plate 88. Clamping cylinders 810 are symmetrically arranged at the bottom of the transverse plate 88. The clamping cylinders 810 are connected to the installation block 87. The clamping operation of the metal part 4 can be facilitated through the clamping cylinders 810.

[0040] Clamping blocks 811 are symmetrically arranged at the bottom of the clamping cylinders 810. The metal part 4 is clamped through the clamping blocks 811, making the metal part 4 not easily fall off.

[0041] During the use process, the qualified metal parts 4 after being detected by the flaw detection component 5 will move along the conveyor line 2 to the blanking component 8. First, the first electric cylinder 83 is started, and the first electric cylinder 83 drives the first sliding table 84 to move horizontally. The first sliding table 84 drives the second electric cylinder 86 to move to the center position of the conveyor line 2 through the second mounting base plate 85. Then, the second electric cylinder 86 is started, and the second electric cylinder 86 drives the mounting block 87 to move downward. The mounting block 87 drives the two clamping cylinders 810 to move downward through the transverse plate 88. By starting the clamping cylinders 810, the clamping cylinders 810 drive the two groups of clamping blocks 811 to clamp the metal parts 4. Then, the reverse operation is performed to carry out the blanking operation on the metal parts 4, eliminating the need for manual blanking, reducing the labor intensity of workers, and improving work efficiency.

[0042] The rest of the structure is the same as that of Embodiment 2.
