In 39, since stub 16 moves upwardly so that the magnetic direction that moving direction is formed with two permanent magnets 15 is mutually perpendicular to, from
And cutting magnetic induction line movement is carried out, since stub 16, coil 18 and electromagnet 38 form closed circuit, to form electricity
Stream, when acting on electromagnet 38, make it have certain magnetism, so as to attract oscillating rod 11, recording pen 12 to
Lower movement, while ensureing that the movement velocity of sliding block 25 in electric sliding rail 14 is consistent with the speed of straight line module motor 21, to
When starting straight line module motor 21, sliding block 25 drives roll paper 23 to move by geometrical clamp 24, to which recording pen 12 can rolled up
The surface of paper 23 draws trace, and when the degree of protrusion is larger, the area that stub 16 enters magnetic field is different, to the electricity generated
It is also different to flow size, and then electromagnet 38 is different to the attraction of oscillating rod 11, so that recording pen 12 is in roll paper 23
In the trace depth that leaves it is different；
Last operation worker unloads roll paper 23, by the trace for observing 23 surface of roll paper, you can judge that the furniture is smooth
Whether degree is qualified, and trace is deeper, it can be said that bright degree of convexity is larger, conversely, similarly；In addition, due to indicating quarter in roll paper 23
Line is spent, so as to clearly know which place of the furniture surface has protrusion.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
