As shown in fig. 1, 2 and 3, the present application provides a wire passing device 100, which includes a fixing base 11, a guide rod 12, a guide wheel 13 and a limiting mechanism 14. The fixing base 11 includes a first connection member 111, both ends of the guide bar 12 are connected to the fixing base 11 through the first connection member 111, the guide bar 12 includes an axis 101, and the guide bar 12 can be rotated along the axis 101 by the first connection member 111.

The limiting mechanism 14 is used for limiting the guide wheel 13 to move along the axis 101, and the limiting mechanism 14 is connected to the guide rod 12. It can be understood that in the production process of the diamond wire, in order to realize the functions of supporting the wire and giving the wire net, a wire passing device 100 is generally required, a plurality of guide wheels 13 are generally arranged on the wire passing device 100, the diamond wire is attached to the surface of the guide wheel 13 along the direction perpendicular to the axis of the guide wheel, and the guide wheel 13 is driven by the diamond wire to rotate in the wire passing process. The more the number of guide wheels 13 is, the more the number of diamond wires that can be simultaneously threaded is within a reasonable range, and the higher the working efficiency of the wire threading device 100 is. Through the above arrangement, the connection structure of the conventional guide bar 12 and the fixing base 11 is changed, the guide bar 12 is connected to the fixing base through the first connecting piece 111, the guide wheel 13 is connected to the guide bar 12 through the second connecting piece 131, and the guide bar 12 and the guide wheel 13 can independently rotate along the axis 101. So that the operation states of the guide bar 12 and the guide wheel 13 are not affected by each other, and thus the overall working efficiency of the wire passing device 100 can be improved. In the actual working process of the wire passing device 100, when one or more guide wheels 13 are blocked and cannot rotate, the guide wheels 13 and the guide rods 12 form a whole body without relative movement, the guide rods 12 rotate along the axis 101 of the guide rods 12 under the driving of the diamond wires, and the diamond wires can be prevented from being damaged due to larger friction force between the diamond wires and the guide wheels 13. Meanwhile, if the guide rod 12 is blocked, the guide wheel 13 can still rotate by itself through the second connecting piece 131, so as to ensure the overall production stability and service life of the wire passing device 100. After an operator finds that the guide rod 12 or the guide wheel 13 is blocked in the diamond wire passing process, the guide rod 12 or the guide wheel 13 can be repaired or replaced after the batch production is completed, and the working efficiency of the whole production is improved on the basis of ensuring the quality of the diamond wire. In the application, the guide rod 12 and the guide wheel 13 can rotate simultaneously under the drive of the diamond wire, so that the wire passing speed of the diamond wire is increased, and the working efficiency of the wire passing device 100 is further improved. As shown in fig. 4 and 5, the first connector 111 further includes a first lubrication portion 1111, the first lubrication portion 1111 is disposed near the guide rod 12, and the second connector 131 further includes a second lubrication portion 1311, the second lubrication portion 1311 is disposed near the guide rod 12.

Specifically, first link 1114 is rotatable along axis 101, and second link 131 includes a second link 1312, second link 1312 being rotatable along axis 101 as well. The guide bar 12 is disposed through the first and second connection parts 1114 and 1312. Through the arrangement, the guide rod 12 can rotate relative to the fixed seat 11, so that the guide rod 12 can rotate in time to prevent the diamond wire from being damaged due to friction under the condition that the guide wheel 13 is blocked and cannot rotate. Meanwhile, the guide wheel 13 can also rotate relative to the guide rod 12 directly through the second connecting portion 1312, so as to prevent the guide rod 12 from being blocked and affecting the overall production efficiency of the wire passing device 100. In addition, the supporting portion 1113 and the first connecting portion 1114 may be integrally formed, and the supporting portion 1113 and the first connecting portion 1114 may be integrally formed, so that strength of the first connecting portion 1114 may be enhanced, loosening caused by long-term rotation of the guide rod 12 may be avoided, and assembly process may be reduced, so that manufacturing cost may be reduced. The support portion 1113 and the first connection portion 1114 may be assembled after being manufactured separately.

The setting of the clamping and detecting mechanism 15 can monitor the working condition of the wire passing device 100 at any time, thereby ensuring that an operator can respond to the clamping and the detecting of the guide rod 12 or the guide wheel 13 in real time and improving the production efficiency and the product quality of the wire passing device 100. Specifically, the click detection mechanism 15 includes a sensing component 151, the sensing component 151 is disposed on the guide rod 12 and near an end of the guide rod 12, the click detection mechanism 15 further includes a sensing component 152, and the sensing component 152 is disposed on the fixing seat 11 and near the sensing component 151. The sensing component 151 can detect whether the rotation of the guide rod 12 and the guide wheel 13 is within a normal range, the sensing component 152 outputs a signal to the display screen after receiving the abnormal information and displays a corresponding state on the display screen, and an operator can judge the clamping condition of the guide rod 12 and the guide wheel 13 according to the display of the display screen. The arrangement of the sensing assembly 151 near the end of the guide rod 12 enables the sensing assembly 151 to sense finer changes, thereby improving the sensitivity of the sensing assembly 151. More specifically, sensing assembly 151 may include a shutter, sensing assembly 152 may include a photoelectric sensor, and the click-on detection mechanism 15 may further include a sound generator 153 connected to the photoelectric sensor. When the diamond wire passes through the wire, the guide wheel 13 is driven to rotate at a constant speed, and the guide wheel 13 drives the guide rod 12 to rotate, so that the light shield intermittently triggers the photoelectric sensor, and the triggering time intervals of the photoelectric sensor are the same. If the guide rod 12 or the guide wheel 13 is blocked, the friction force between the guide wheel 13 and the guide rod 12 is changed, so that the triggering time of the photoelectric sensor is changed. After the photoelectric sensor recognizes the change of the trigger time, namely, after the photoelectric sensor recognizes the clamping state, the corresponding state signal can be output, and meanwhile, the sounder 153 can be utilized to send out an alarm so as to remind an operator to adjust the parts of the wire passing device 100, which are clamped, the normal operation of the guide rod 13 and the guide wheel 13 is ensured, the abrasion of the diamond wire and the guide wheel 13 is avoided, and the overall working efficiency and the service life of the wire passing device 100 are improved.
