[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] It is understood that although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims or the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0045] At present, blade sharpness testing equipment can only test the sharpness of the straight edge of the kitchen knife during the longitudinal and transverse cutting processes. However, due to the shape of the circular blade and its special application in industrial production, the existing blade sharpness testing equipment cannot reflect the sharpness of the circular blade during rotary cutting in a normal working environment.

[0046] Based on this, the embodiments of the present application provide a circular blade sharpness detection device, method, apparatus and medium. By setting a vertical slide rail, the drive motor can move along the Y-axis and X-axis directions. Since the blade to be detected is installed on the drive motor, the position of the blade to be detected can be adjusted through the vertical slide rail to avoid misaligned cutting and improve the accuracy of detection. By driving the blade to be detected by the drive motor, the scene of the circular blade rotating and cutting in a normal working environment can be simulated. In addition, by setting a pressure sensor inside the mounting part, the pressure value of the test material during the circular blade cutting process can be obtained, and then the sharpness of the blade to be detected can be judged by the pressure value.

[0047] First, refer to Figure 1 , Figure 1A schematic diagram of the structure of a circular blade sharpness detection device provided in an embodiment of the present application.

[0048] It is understood that the circular blade sharpness detection device includes a chassis 100, a fixed frame 600, a horizontal slide rail 200, a vertical slide rail 300, a drive motor 400 and a controller 700. The fixed frame 600 is arranged above the chassis 100, and the fixed frame 600 includes a mounting member 610 for fixing the test material. By fixing the test material by the mounting member 610, the test material can be prevented from shaking during the cutting process of the blade 500 to be detected. In addition, a pressure sensor for obtaining the cutting pressure value of the test material during the circular blade cutting process is also provided inside the mounting member 610. The horizontal slide rail 200 is horizontally arranged on one side of the fixed frame 600, one end of the vertical slide rail 300 is slidably mounted on the horizontal slide rail 200, and the drive motor 400 is slidably mounted on the vertical slide rail 300. By sliding the vertical slide rail 300 in the horizontal slide rail 200 and the drive motor 400 in the vertical slide rail 300, the position of the blade 500 to be detected can be adjusted to avoid misaligned cutting and improve the accuracy of detection. By driving the blade 500 to be tested through the driving motor 400, a scene of a circular blade rotating and cutting in a normal working environment can be simulated. The controller 700 is respectively connected to the horizontal slide rail 200, the vertical slide rail 300, the driving motor 400 and the pressure sensor. The controller 700 is used to control the movement of the vertical slide rail 300 in the horizontal slide rail 200, the movement of the driving motor 400 in the vertical slide rail 300, the working state of the driving motor 400, and the cutting pressure value of the test material during the cutting process is obtained through the pressure sensor.

[0049] It should be noted that the driving motor 400 includes a telescopic shaft 420 and a driving assembly 410 for driving the telescopic shaft 420 to rotate, and a mounting block is disposed at one end of the telescopic shaft 420 away from the driving assembly 410. When the blade 500 to be detected is mounted on the mounting block, the driving assembly 410 drives the telescopic shaft 420 to rotate, which drives the blade 500 to be detected to rotate. In addition, the distance between the blade 500 to be detected and the driving assembly 410 can be adjusted through the telescopic effect of the telescopic shaft 420.

[0050] It should be noted that when it is necessary to detect the blade 500 to be detected, the position of the blade 500 to be detected can be adjusted by the horizontal slide rail 200, the vertical slide rail 300 and the telescopic shaft 420 so that the center of the circle of the blade 500 to be detected is in the same straight line with the midpoint of the test material to avoid the blade 500 to be detected from cutting misalignment. Then, according to the outer diameter of the blade 500 to be detected, the rotation speed and the descending speed of the drive motor 400 are determined, and according to the rotation speed and the cutting descending speed, the blade 500 to be detected is controlled to cut the test material. Among them, the descending speed of the drive motor 400 is the speed at which the drive motor 400 moves along the vertical slide rail 300 toward the test material. Finally, the cutting pressure value to which the test material is subjected during the cutting process is obtained, and then the sharpness of the blade 500 to be detected is determined according to the cutting pressure value.

[0051] It should be noted that the circular blade sharpness detection device further includes an image sensor for obtaining the outer diameter of the blade 500 to be detected and the material thickness of the test material, and the image sensor is connected to the controller 700 .

[0052] Reference Figure 2 , Figure 2 is a flow chart of a control method of a circular blade sharpness detection device provided in an embodiment of the present application. The control method of the circular blade sharpness detection device can be applied to the above Figure 1 The circular blade sharpness detection device, the control method includes but is not limited to the following steps:

[0053] Step S100, obtaining the outer diameter of the blade to be tested;

[0054] Step S200, determining the rotation speed and descending speed of the driving motor according to the outer diameter of the blade;

[0055] Step S300, controlling the blade to be tested to cut the test material according to the rotation speed and the cutting descent speed;

[0056] Step S400, obtaining the cutting pressure value to which the test material is subjected during the cutting process;

[0057] Step S500, determining the sharpness of the blade to be tested according to the cutting pressure value.

[0058] It is understandable that the working environments corresponding to circular blades of different sizes are not the same, that is, in the actual working environment, the rotation speeds of circular blades of different sizes are not the same. Therefore, the rotation speed of the drive motor can be determined by obtaining the outer diameter of the blade to be detected, wherein the higher the rotation speed, the higher the rotation speed of the blade to be detected. By obtaining the outer diameter of the blade to be detected and determining the working efficiency of the drive motor, the actual working environment of the blade to be detected can be effectively simulated to improve the accuracy of sharpness detection. Since the outer diameters of the blades of different blades to be detected are different, the distances between the blade to be detected and the test material are different. Therefore, the descending speed of the drive motor can be determined by obtaining the outer diameter of the blade to be detected, wherein the descending speed of the drive motor is the speed at which the drive motor moves along the vertical slide toward the test material. For example, the larger the outer diameter of the blade, the slower the descending speed of the drive motor, so that the blade to be detected can fully cut the test material and improve the accuracy of sharpness detection. In addition, by controlling the descending speed of the drive motor, the blade to be detected can be heated before cutting the test material, so that the rotation speed of the blade to be detected reaches a preset rotation speed when cutting. During the cutting process, the pressure value of the test material is negatively correlated with the sharpness of the blade to be tested, that is, the greater the pressure value of the test material, the sharper the blade to be tested. Therefore, the cutting pressure value of the test material during the cutting process is obtained, and the sharpness of the blade to be tested is determined according to the cutting pressure value, wherein the sharpness is characterized by the sharpness of the blade to be tested.

[0059] Specifically, during the cutting process, the test material will be continuously subjected to the pressure of the blade to be cut, so the cutting pressure value may include multiple first pressure values, and the first pressure value is the pressure that the test material is subjected to at different time periods during the cutting process. Since the blade to be tested is a rotating cutting test material, the pressure value to which the test material is subjected may change during the cutting process, so the multiple first pressure values ​​can be sorted from large to small to obtain the maximum pressure value, and then the sharpness of the blade to be tested can be determined based on the maximum pressure value to improve the accuracy of sharpness detection.

[0060] Specifically, in some embodiments, an average value of a plurality of first pressure values ​​may be calculated, and then the sharpness of the blade to be detected may be determined based on the average value.

[0061] It should be noted that after the blade to be detected completes cutting and the sharpness of the blade to be detected is determined, the vertical slide rail can be controlled to control the drive motor to move to the starting position, that is, the blade to be detected is controlled to move to the starting position.

[0062] Reference Figure 3 , Figure 3is another flow chart of the control method of the circular blade sharpness detection device provided in the embodiment of the present application, including but not limited to the following steps:

[0063] Step S310, obtaining the cutting depth of the blade to be detected;

[0064] Step S320: When the cutting depth reaches a preset depth, the driving motor is controlled to stop working.

[0065] It is understandable that if the cutting depth of the blade to be tested is greater than a certain level during the test, it may overcut and bottom out, causing the blade to be tested to contact the device, resulting in damage to the device and the blade to be tested. Therefore, during the cutting process of the blade to be tested, the cutting depth of the blade to be tested can be obtained. When the cutting depth reaches a preset depth, the drive motor is controlled to stop working, thereby avoiding damage to the blade to be tested and the circular blade sharpness detection device, and improving the service life of the circular blade sharpness detection device, wherein the preset depth is the depth at which the blade to be tested may overcut and bottom out.

[0066] Specifically, due to the different blade outer diameters, under the same descent speed, the cutting depth of the blade to be tested with a larger blade outer diameter will be deeper than that of the blade to be tested with a smaller blade outer diameter. The allowable cutting depth is different due to the different material thickness of the test material. Therefore, the preset depth can be determined based on the material thickness of the test material and the blade outer diameter of the blade to be tested.

[0067] Reference Figure 4 , Figure 4 is another flow chart of the control method of the circular blade sharpness detection device provided in the embodiment of the present application, including but not limited to the following steps:

[0068] Step S330, obtaining the center of the circle of the blade to be tested and the midpoint of the test material;

[0069] Step S340, determining the position adjustment parameters of the blade to be detected according to the center and the midpoint of the circle;

[0070] Step S350, moving the blade to be inspected according to the position adjustment parameter so that the center and the midpoint are on the same horizontal line.

[0071] It is understandable that different blades to be tested have different outer diameters. If a unified cutting direction is used, it may cause miscutting. Therefore, before controlling the blade to be tested to cut the test material, the center of the circle of the blade to be tested and the midpoint of the test material can be obtained, and then the position adjustment parameters of the blade to be tested can be determined based on the center of the circle and the midpoint, where the position adjustment parameters include the telescopic distance of the telescopic shaft and the moving distance of the vertical slide in the horizontal slide. According to the position adjustment parameters, the telescopic shaft and / or the vertical slide are driven to move the blade to be tested so that the center of the circle and the midpoint are on the same horizontal line to improve the cutting accuracy.
