[0031] Working principle:

[0032] When the rubber wire tension test is needed, the lower end of the rubber wire is placed in the second block 12, then the second bolt 13 is screwed, the second bolt 13 drives the second vertical plate 14 to move to the right through the bearing, the second vertical plate 14 moves in contact with the rubber wire and is fixed on the second block 12, then the upper end of the rubber wire is placed in the first block 8 after the lower end of the rubber wire is fixed, then the first bolt 9 is screwed, the first bolt 9 drives the first vertical plate 10 to move to the right through the bearing, the first vertical plate 10 moves in contact with the rubber wire and is fixed on the block 8, and the first bolt 9 is stopped after the upper end of the rubber wire is fixed, so that the rubber wire is fixed through the above method;

[0033] Subsequently, the external power supply of the second servo motor 202 is turned on and started, the second servo motor 202 drives the first gear 203 to rotate, the first gear 203 drives the second gear 208 to rotate (the rotation directions of the first gear 203 and the second gear 208 are opposite), the first gear 203 and the second gear 208 both drive the rod body 204 to rotate (the two rod bodies 204 rotate inward), the rod body 204 drives the horizontal plate 205 to move upward through the sliding groove (since the outer wall of the rod body 204 is relatively smooth, the friction between the rod body 204 and the horizontal plate 205 can be reduced, thereby preventing damage to the rod body 204), the horizontal plate 205 drives the first block 8 to move upward, thereby driving the upper part of the fixed rubber wire to move upward, since the first block 8 drives the upper part of the rubber wire to move upward, and the second block 12 does not change the position of the lower part of the rubber wire, when the first block 8 moves upward, the rubber wire is stretched to perform a tensile test thereon;

[0034] The position of the pointer 11 on the first block 8 pointing to the scale line 207 is observed, thereby controlling the moving distance of the block 8, so that the stretching length of the rubber wire can be accurately known (the moving distance of the block 8 can be controlled by the worker according to the stretching distance of the rubber wire), after the tensile test of the rubber wire is completed, the second servo motor 202 is reversed to reset the position of the first block 8, after the first block 8 is reset, the second servo motor 202 is turned off, then the first bolt 9 and the second bolt 13 are reversed according to the above-mentioned manner to cancel the fixation of the rubber wire, then the worker manually places the rubber wire on the plate body 6, then the CCD camera 4 detects the rubber wire (the CCD camera utilizes the unique properties of the charge-coupled device to generate images, when the rubber wire is irradiated by the CCD camera, the photons interact with the electrons in the semiconductor material when the image and the light source are on the CCD sensor, the electron-hole pairs are transferred to the output nodes of the CCD under the action of the electric field, then through an amplifier, the readable signal is converted, the scale signal background program is connected, thereby identifying the signals of the rubber wire with a broken end and the rubber wire with a complete end, and the start of the third servo motor 302 is also connected with the program, thereby driving the third servo motor 302 to drive the cylinder 306 to move, the CCD camera 4 is a prior art, and the above-mentioned operation can be realized in the prior art);

[0035] When the rubber wire is qualified, the external power supply of the first servo motor 5 is turned on and started, the first servo motor 5 drives the plate body 6 to rotate by 90 degrees, the plate body rotates by 90 degrees to generate an inclination, the qualified rubber wire falls on the right barrel 6 on the support plate 305 along with the inclination of the plate body 6, thereby recycling the qualified rubber wire (such as Figure 2 ), after the rubber wire is recycled, the first servo motor 5 is reversed to reversely rotate the plate body 6 by 90 degrees to reset, after the plate body 6 is reset, the first servo motor 5 is turned off;

[0036] When the rubber wire is unqualified, the third servo motor 302 drives the third gear 303 to rotate clockwise, thereby driving the rack 304 to move right, the rack 304 moves right, thereby driving the two cylinder bodies 306 to move right, after the left cylinder body 306 on the support plate 305 moves to the lower side of the plate body 6, the third servo motor 302 is closed, then the first servo motor 5 is started according to the above mode to make the plate body 6 rotate 90 degrees, and the unqualified rubber wire is dropped into the left cylinder body 306 on the support plate 305, thereby the unqualified rubber wire is recycled (the third servo motor 302 is reversely rotated to make the two cylinder bodies 306 move left to reset), through the above mode, the qualified rubber wire and the unqualified rubber wire are respectively placed in the two cylinder bodies 306, thereby workers do not need to distinguish in the later stage, then the workers continue to carry out the tension test work on the subsequent rubber wire.
