Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the blade visual inspection apparatus of the present embodiment can be used for appearance and size inspection of a plurality of blades 100. In the detection process, a plurality of blades 100 are fed in a manner that the waste tape 200 comes, that is, the plurality of blades 100 are sequentially connected to the waste tape 200, and the waste tape 200 is used for conveying the material, so that the plurality of blades 100 can be sequentially, continuously and accurately fed. The blade vision inspection device of the embodiment can perform full inspection on a plurality of blades 100 which are fed.

Referring to fig. 2 and 3, the visual blade inspection apparatus of the present embodiment mainly includes a material conveying mechanism 1, a detecting mechanism 2, a material cutting mechanism 3, and at least two material pressing mechanisms 4. The material conveying mechanism 1 includes a material guide plate 11 for guiding the waste material belt 200, a first driving unit 12, a driven wheel 13 and a driving wheel 14 disposed on an output shaft of the first driving unit 12, the first driving unit 12 is used for driving the driving wheel 14 to rotate, the driven wheel 13 is used for cooperating with the driving wheel 14 to drive the waste material belt 200 to move along the material guide plate 11, and preferably, the driving wheel 14 is used for further providing anti-slip patterns on a surface tangent to the waste material belt 200 to improve the transmission reliability thereof. The detection mechanism 2 is disposed on the feeding side of the material conveying mechanism 1 to detect the appearance and size of the blade 100. The material cutting mechanism 3 is arranged between the detection mechanism 2 and the material conveying mechanism 1, and is used for cutting the defective blade 100 away from the waste belt 200, that is, the material cutting mechanism 3 is located at the discharging side of the detection mechanism 2, after the detection unit detects the defective blade 100, when the defective blade 100 runs to the material cutting mechanism 3, the material cutting mechanism 3 can cut off the defective blade 100, so that the defective blade 100 is separated from the waste belt 200, and the blade 100 detected by the detection device of the embodiment is guaranteed to be a good product. Because the waste material belt 200 is also made of steel and has certain rigidity, the waste material belt is easy to arch upwards to separate from the surface of the guide plate 11 in the conveying process, so that the pressing mechanism 4 can be adopted to limit the waste material belt 200 in the vertical direction, and the waste material belt 200 is prevented from separating from the guide plate 11 in the conveying process, thereby influencing the detection structure.

As shown in fig. 3, the material conveying mechanism 1 of this embodiment may further include a first bracket 15 and a first cylinder 16 disposed on the first bracket 15, the driven wheel 13 is disposed on a piston rod of the first cylinder 16, and the first cylinder 16 may adjust a position relationship between the driven wheel 13 and the driving wheel 14, so that a gap between the driven wheel 13 and the driving wheel 14 can meet a transmission requirement of the waste tape 200.

As shown in fig. 2, the detection mechanism 2 of the present embodiment includes a second carriage 21 and a CCD camera 22 provided on the second carriage 21. The second support 21 may be disposed substantially beside the material guide plate 11, and the CCD camera 22 may be disposed substantially above the material guide plate 11. Of course, the detecting mechanism 2 may further include a light source for providing light to the CCD camera 22, and the CCD camera 22 may detect the appearance and size of the blade 100.

As shown in fig. 4, the blanking mechanism 3 of the present embodiment mainly includes a third bracket 31, a second cylinder 32 provided on the third bracket 31, and a punch 33 provided on a piston rod of the second cylinder 32. The second cylinder 32 may be connected to the detecting mechanism 2 through an electronic control system, and when the detecting mechanism 2 detects a defective blade 100, the information is fed back to the electronic control system, and the electronic control system controls the second cylinder 32 to operate to cut the defective blade 100 off the waste tape 200.

As shown in fig. 5, the pressing mechanism 4 of the present embodiment mainly includes a fourth support 41 disposed on the material guiding plate 11 and a roller 42 disposed on the fourth support 41, and the roller 42 is configured to press on the waste tape 200 to prevent the waste tape 200 from moving up and down. Of course, the pressure exerted by the rollers 42 on the waste tape 200 is not excessive so as to interfere with the movement of the waste tape 200. The pressing mechanisms 4 are uniformly arranged along the moving direction of the waste tape 200 to improve the stress uniformity of the waste tape 200.

As shown in fig. 2, the visual blade detecting apparatus of this embodiment may further include a plurality of limiting units 5 and a second driving unit 6 for driving the limiting units 5 to move toward and away from the material guiding plate 11, where the limiting units 5 are used to abut against the blade 100 in a direction perpendicular to the movement direction of the waste material belt 200, so as to further improve the movement accuracy of the waste material belt 200, ensure the position accuracy of the blade 100 when moving below the CCD camera 22, and ensure the reliability of the detection result.

Further, as shown in fig. 6, the limiting unit 5 of the present embodiment includes a main body 51, and one side of the main body 51 facing the material guide plate 11 is provided with a groove 511, and the groove 511 penetrates both ends of the main body 51 in the moving direction of the waste material belt 200, so that the waste material belt 200 can pass through the main body 51. Two tungsten steel bars 52 are arranged in the groove 511 in an up-and-down opposite mode, and the gap between the two tungsten steel bars 52 is smaller than the maximum thickness of the blade 100. More specifically, the blade 100 generally comprises a cutter body and a cutting edge which are connected with each other, the thickness of the cutting edge is gradually reduced along the direction away from the cutter body, the gap between the two tungsten steel bars 52 is not more than the maximum thickness of the cutting edge, so that when the second driving unit 6 drives the limiting unit 5 to move towards the waste tape 200, the cutting edge of the blade 100 can be clamped between the two tungsten steel bars 52, and the two tungsten steel bars 52 can limit the cutting edge 100. Because the wolfram steel bar 52 has a high hardness (at least greater than the hardness of the blade 100), the blade edge is difficult to cut into chips on the wolfram steel bar 52, which prevents the chips from fraying the blade edge.

As shown in fig. 2, the visual blade inspection apparatus of this embodiment may further include a mounting plate 7 for connecting with the second driving unit 6, wherein the plurality of limiting units 5 are disposed on the mounting plate 7, and when the second driving unit 6 drives the mounting plate 7 to move, the plurality of limiting units 5 are driven to move simultaneously.

1. by adopting the online detection mode of the CCD camera 22, the appearance and the size of all the blades 100 can be detected efficiently and accurately, the detection reliability is improved, and the outflow of defective products is avoided.

2. The material pressing mechanism 4 and the limiting unit 5 can ensure that the waste material belt 200 stably and accurately runs, and when the blade 100 runs to the detection mechanism 2, the position of the blade is the same as the preset position, so that the detection reliability is improved.

3. The cutting mechanism 3 can timely cut the bad blade 100 detected by the detection mechanism 2 away from the waste belt 200, so that the flow of the bad products is avoided.
