[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1 and Figure 2 As shown, the embodiment of the present application discloses a novel scratch detection device including: a mounting frame 1; a storage rack 11, which is arranged on the mounting frame 1 and is used to place the workpiece to be detected; a moving component 2, which is movably arranged on the mounting frame 1 and is located above the storage rack 11; a probe 3, which is telescopically arranged on the moving component 2; a spring 31, which is arranged in the moving component 2 and is used to support the probe 3 to contact the workpiece; a displacement sensor, which is arranged in the moving component 2 and is used to detect the displacement change of the probe 3; a terminal processor, which is electrically connected to the displacement sensor and is used to output the displacement change of the probe 3; and a driving component, which is used to drive the moving component 2 to move along a specified path.

[0019] During specific use, the workpiece to be inspected is first placed on the rack 11, one end of the probe 3 is pressed against the outer surface of the workpiece, and the spring 31 is squeezed for a certain length; then the moving component 2 is driven by the driving component to move along the specified path. When the probe 3 moves over the surface with defects, the spring 31 will push the end of the probe 3 to fit the bottom surface of the defect. The displacement sensor will synchronously record the displacement change of the probe 3, and convert it into an electrical signal to be transmitted to the terminal processor (which can be a CPU). The displacement change of the probe 3 is output through the terminal processor to obtain the true situation of the workpiece surface.

[0020] By using the utility model, scratches on the surface of the workpiece can be automatically detected, manual labor can be reduced, and detection efficiency can be improved; moreover, the utility model can record the actual situation of the scratch defect, the depth and width of the scratch defect can be known, and a more accurate detection result can be obtained.

[0021] Specifically, the device further includes: a first moving track 41, which is arranged on the rack 11 along the length direction of the workpiece for the movable part 2 to slide; and a second moving track 42, which is arranged on the rack 11 along the width direction of the workpiece for the movable part 2 to slide.

[0022] It is worth mentioning that the driving component includes at least two linear motors, which are used to drive the moving component 2 to move along the first moving track 41 and the second moving track 42 respectively; the displacement sensor can be a laser displacement sensor, which is composed of a laser, a laser detector and a measuring circuit; it can be known that the specific installation method of the linear motor and the laser displacement sensor is a well-known technology in the field and will not be repeated here.

[0023] Specifically, the device also includes: a flange 5, which is installed on the movable part 2; a plurality of supporting parts 51, which are movably arranged in the mounting hole; a plurality of ball bearings 52, which are rollably arranged at one end of the supporting part 51, and are used to abut against the workpiece; a plurality of supporting parts 51 are installed on the flange 5 along a circular array with the probe 3 as the center of the circle, and the movable part 2 is supported by the ball bearings 52, and the movable part 2 can be rolled and supported, thereby improving the stability of the probe 3 moving along the workpiece.

[0024] Furthermore, the support component 51 is installed on the flange 5 by threaded connection. After the probe 3 is worn, the user can adjust the height of the support component 51 by twisting the support component 51, thereby extending the service life of the probe 3.

[0025] Reference Figure 3As shown, the device also includes: a lifting platform 61, which is arranged below the rack 11; a plurality of rolling support components 51, which are rotatably installed on the lifting platform 61; a lifting component 64, which is used to drive the lifting platform 61 to perform lifting movement in the vertical direction and pass through the rack 11; when it is necessary to pick up and place the workpiece, the lifting platform 61 is driven to rise in the vertical direction by the lifting component 64, and the rolling support component 51 can pass through the rack 11 and protrude a certain height from the rack 11. The rolling support component 51 and the workpiece are in rolling contact, which is convenient for the user to drag the workpiece and to pick up and place the workpiece.

[0026] Specifically, the rolling support component 51 includes: a roller 62; a support rod 63, which is set at both ends of the roller 62, and the roller 62 is rotatably installed on the roller 62 through a bearing; the lifting component 64 can use a hydraulic cylinder to drive the lifting platform 61 to rise and fall.
