Detailed Embodiments

[0017] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are used to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0018] A PCB drill bit milling cutter blade detection machine, as Figures 1 - 4 shown, includes a support base 1, a first conveyor belt 2, a mounting plate 3, a first electric slide rail 31, a second electric slide rail 32, a first cylinder 4, a connecting plate 41, a rotating mechanism, a detection camera 7, a second cylinder 8, a clamping mechanism and a second conveyor belt 10. A first conveyor belt 2 is installed on the left side of the support base 1. Five grooves are formed on the conveyor belt of the first conveyor belt 2, and these grooves are used to place the drill bit milling cutter. Five mounting plates 3 are fixedly connected to the top of the support base 1, and the mounting plates 3 are all located above the corresponding grooves of the first conveyor belt 2. The left sides of the bottoms of the mounting plates 3 are fixedly connected with first electric slide rails 31, so that the drill bit milling cutter is located between two detection cameras 7. The right sides of the bottoms of the mounting plates 3 are fixedly connected with second electric slide rails 32. The slider ends of the first electric slide rails 31 are fixedly connected with first cylinders 4, and the piston rods of the first cylinders 4 are fixedly connected with connecting plates 41. A rotating mechanism is connected to the connecting plates 41. At least two detection cameras 7 are fixedly connected to the middle of the support base 1. Whether the blade of the drill bit milling cutter is qualified is identified through the detection cameras 7. The detection cameras 7 are all electrically connected to a controller, and the controller is electrically connected to the second electric slide rails 32. The slider ends of the second electric slide rails 32 are fixedly connected with second cylinders 8, and clamping mechanisms are connected to the piston rods of the second cylinders 8. A second conveyor belt 10 is installed on the right side of the support base 1. The first electric slide rail 31 is used to drive the rotating mechanism on the first cylinder 4 to move, and the second electric slide rail 32 is used to drive the clamping mechanism on the second cylinder 8 to move.

[0019] When it is necessary to detect the rake face of the drill bit milling cutter, place the drill bit milling cutter on the first conveyor belt 2. The first conveyor belt 2 moves the drill bit milling cutter to directly below the rotating mechanism. The rotating mechanism is moved downward by the first cylinder 4 to clamp the drill bit milling cutter. Then, the rotating mechanism is moved to the right by the first electric slide rail 31, so that the drill bit milling cutter is located between the two detection cameras 7. After the detection is completed, the rotating mechanism is moved upward by the first cylinder 4, and the clamping mechanism clamps the drill bit milling cutter. The detection camera 7 controls the distance that the second electric slide rail 32 moves to the right through the controller on it. The drill bit milling cutters with qualified rake faces will be placed on one side of the second conveyor belt 10, and the drill bit milling cutters with unqualified rake faces will be placed on the other side of the second conveyor belt 10. Then, the first electric slide rail 31 and the second electric slide rail 32 are reset, and the next round of detection of the rake face of the drill bit milling cutter is carried out. By using the detection camera 7 to detect the qualification of the rake face of the drill bit milling cutter, a large amount of labor costs can be saved, and the qualified and unqualified drill bit milling cutters are classified and placed on the second conveyor belt 10 for transportation, which is convenient for the detection and classification of the drill bit milling cutters.

[0020] As Figure 1 and Figure 2 shown, the rotating mechanism includes a rotating disk 42, a first double-acting cylinder 5, clamping plates 51 and a motor 6. The middle parts of the connecting plates 41 are all rotatably connected with the rotating disk 42. The right sides of the rotating rods are all fixedly connected with the first double-acting cylinder 5. The telescopic rods of the first double-acting cylinder 5 are all fixedly connected with the clamping plates 51. Before the rotating mechanism clamps the drill bit milling cutter, the telescopic rods of the first double-acting cylinder 5 are in the extended state, so that the front and rear clamping plates 51 are far away from each other, facilitating the clamping of the drill bit milling cutter. Motors 6 are installed on the rear sides of the rotating disks 42, and the output shafts of the motors 6 are fixedly connected with the rotating disks 42. By rotating the drill bit milling cutter through the motor 6, the detection camera 7 can detect the entire rake face of the drill bit milling cutter.

[0021] The rotating mechanism moves downward through the first cylinder 4, so that the drill bit milling cutter is located between the front and rear clamping plates 51. By retracting the telescopic rods of the first double-acting cylinder 5, the clamping plates 51 can be made to approach each other to clamp the drill bit milling cutter. When the drill bit milling cutter is moved between the two detection cameras 7, the rotating disk 42 is rotated by the motor 6. The rotating disk 42 drives the first double-acting cylinder 5 and the clamping plates 51 to rotate, thereby driving the drill bit milling cutter to rotate. After the detection is completed, the clamping mechanism clamps the drill bit milling cutter. By extending the telescopic rods of the first double-acting cylinder 5, the drill bit milling cutter can be separated from the rotating mechanism, so as to carry out subsequent operations.

[0022] As Figure 1 and Figure 3As shown in the figure, the clamping mechanism includes a second double-acting cylinder 9 and an arc-shaped clamp 91. The telescopic rods of the second cylinders 8 are fixedly connected with the second double-acting cylinder 9, and the telescopic rods of the second double-acting cylinder 9 are fixedly connected with the arc-shaped clamp 91. The two arc-shaped clamps 91 on the same second double-acting cylinder 9 can be close to each other to clamp and fix the drill bit milling cutter. Initially, the telescopic rod of the second double-acting cylinder 9 is in the extended state. When using the clamping mechanism to clamp the drill bit milling cutter, the arc-shaped clamp 91 clamps the drill bit milling cutter by retracting the telescopic rod of the second double-acting cylinder 9. By extending the telescopic rod of the second double-acting cylinder 9, the drill bit milling cutter can be separated from the clamping mechanism, so that the drill bit milling cutter can be placed on the second conveyor belt 10, facilitating the classified placement of the inspected drill bit milling cutters.

[0023] As Figure 4 shown, it also includes a support plate 22. The support plate 22 is fixedly connected inside the first conveyor belt 2 and is located at the bottom of the upper conveyor belt of the first conveyor belt 2. When the drill bit milling cutter is on the first conveyor belt 2, the support plate 22 can support the first conveyor belt 2 to prevent the first conveyor belt 2 from bending due to the weight of the drill bit milling cutter, thus avoiding the situation that the rotation mechanism cannot correctly clamp the drill bit milling cutter on the first conveyor belt 2 due to the bending of the first conveyor belt 2.

[0024] As Figure 1 and Figure 4 shown, it also includes a baffle 21 and a partition plate 101. The baffle 21 is fixedly connected to the right side of the first conveyor belt 2. When the drill bit milling cutter is placed on the first conveyor belt 2, the tip of the drill bit of the drill bit milling cutter contacts the baffle 21. The baffle 21 can make the drill bit milling cutter placed in the correct position on the first conveyor belt 2, ensuring that the rotation mechanism can correctly clamp the drill bit milling cutter. The partition plate 101 is fixedly connected to the middle of the second conveyor belt 10. The partition plate 101 can separate the drill bit milling cutters on the left and right sides of the second conveyor belt 10 to prevent the drill bit milling cutters with different qualification degrees from being mixed with each other.

[0025] As Figure 2 and Figure 3 shown, it also includes a rubber pad 52 for protecting the drill bit milling cutter. Rubber pads 52 are fixedly connected to the sides where the clamping plates 51 are close to each other and the arc-shaped clamps 91 are close to each other. When the rotation mechanism and the clamping mechanism clamp the drill bit milling cutter, the rubber pad 52 can increase the friction between the drill bit milling cutter and the clamping plates 51 and the arc-shaped clamps 91, and at the same time, can protect the drill bit milling cutter from being scratched by the clamping plates 51 and the arc-shaped clamps 91.

[0026] The above has introduced this application in detail. Specific examples are used in this text to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
