In the process that the wire 8 is clamped, the distance between the two connecting plates 132 is detected through the infrared distance measuring instrument 6, the working state of the first air cylinder 137 is detected through the PLC, and when the first air cylinder 137 is detected to be out of work and the distance between the two connecting plates 132 is detected to be gradually increased, the auxiliary positioning assembly 9 and the auxiliary clamping assembly 4 are controlled to be opened. After PLC controller detected unusual promptly, earlier through auxiliary positioning subassembly 9 with wire rod 8 press from both sides tightly to auxiliary clamping subassembly 4 is to the centre gripping of wire rod 8, after auxiliary clamping subassembly 4 centre gripping action was carried out, auxiliary positioning subassembly 9 will loosen wire rod 8, thereby makes the pretreatment of wire rod 8 can normal operating.

In the process of the pretreatment of the wire 8, the distance between the two connecting plates 132 is detected through the infrared distance measuring instrument 6, the working state of the first air cylinder 137 is detected through the controller, the distance between the two connecting plates 132 is detected by the PLC controller to exceed the set distance, and when the first air cylinder 137 is not in the working state through the PLC controller, firstly, the PLC controller controls the stepping motor 23 to stop working, and the alarm 62 is started to remind a worker of the equipment of failure. Secondly, the PLC controller controls the third cylinder 93 to start, that is, the auxiliary positioning assembly 9 is used to position the wire 8, so that the wire 8 is not easy to slide off the bedplate 3 due to its own weight. After the auxiliary positioning assembly 9 is used for positioning the wire 8, the PLC controller will control the second cylinder 47 to start, that is, the wire 8 is clamped by the auxiliary clamping assembly 4. After the wire 8 is clamped by the auxiliary clamping component 4, the PLC controller resets the telescopic rod of the third cylinder 93 of the controller, namely, the auxiliary positioning component 9 and the wire 8 are disconnected. And finally, the PLC controls the stepping motor 23 to start to drive the wire 8 to carry out pretreatment.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
