When the multi-directional cutting device is used, a sample 80 to be cut is placed on the clamping mechanism 20, the clamping mechanism 20 clamps and fixes the sample 80, then the multi-directional moving device 100 drives the cutting knife to repeatedly perform descending, transverse moving, ascending, longitudinal moving and the like, so that multiple times of transverse cutting operation can be realized on the sample 80, and the force applied by the cutting knife 70 on a paint film can be realized by adjusting the multi-directional moving device 100 to control the downward moving distance of the cutting knife 70. After all the transverse cutting operations are finished, the rotating mechanism 30 controls the clamping mechanism 20 to drive the sample 80 to rotate 90 degrees, and transverse cutting operations are performed on the paint film of the sample 80 for multiple times, so that the grid cutting treatment of the paint film of the sample 80 can be completed.

In order to calculate the damage rate of the paint film, the embodiment preferably uses a damage rate calculation program to calculate the area of the cross checkered pattern according to the image information; and the breakage rate calculation program divides the total falling breakage area of the cross checkered patterns and the total area of the cross checkered patterns to obtain the paint film breakage rate of the sample.

After the vertical movement motor 64 is started, the vertical movement screw rod 65 can be driven to rotate, if the vertical movement screw rod 65 rotates clockwise, the vertical movement nut 66 and the supporting arm 63 can be driven to move upwards, and if the vertical movement screw rod 65 rotates anticlockwise, the vertical movement nut 66 and the supporting arm 63 can be driven to move downwards, so that the lifting control of the lattice knife 70 is realized.
As shown in fig. 6, the support arm 63 includes a first arm segment 631, a second arm segment 632, a connection plate 67, and an urging spring 68; the first arm section 631 and the second arm section 632 are both slidably mounted on the vertical translation guide rail 62; the vertical movement screw rod 65 passes through the first arm section 631, and the vertical movement nut 66 is fixedly connected with the first arm section 631; the connecting plate 67 is fixedly connected with the first arm section 631, and the connecting plate 67 extends below the first arm section 631; the second arm section 632 is arranged below the first arm section 631, the second arm section 632 is supported on the connecting plate 67, and the lattice knife 70 is arranged on the second arm section 632; the urging spring 68 is elastically clamped between the first arm section 631 and the second arm section 632.
When the first arm section 631 is driven to move downwards, the force application spring 68 applies a pushing force to the second arm section 632, so that the second arm section 632 can move downwards synchronously with the first arm section 631 until the dicing blade 70 abuts against the paint film of the sample 80 and then stops; at this time, if the first arm section 631 is controlled to move downwards continuously, the pushing force applied by the force application spring 68 to the second arm section 632 can be changed, so that the pressure regulation of the scribing knife 70 and the paint film surface of the sample 80 is realized.
As shown in fig. 6, the supporting arm 63 further includes a force eliminating spring 69, the force eliminating spring 69 is disposed below the second arm section 632, and the force eliminating spring 69 is elastically clamped between the second arm section 632 and the vertical moving support seat 61.
Immediately after the dicing blade 70 abuts on the paint film of the sample 80, the dicing blade 70 already applies an initial pressure to the paint film of the sample 80, so after the addition of the cancel spring 69, the cancel spring 69 can apply an upward pushing force to the second arm section 632 so as to cancel the initial pressure applied by the dicing blade 70, thereby allowing the pressure applied by the dicing blade 70 to be adjusted from zero.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
