[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a quick-change copper plate electrode assembly includes a quick-change electrode head; the quick-change electrode head 1 extends along the bottom of the electrode head base 2, the electrode head base 2 is a cubic block structure, the top end face of the electrode head base 2 is provided with a dovetail groove 5, the dovetail groove 5 is laterally inserted with a copper plate 3, and the front and rear ends of the copper plate 3 are respectively connected to the first pole 8 and the second pole 7 built into the electrode head base 2. Among them, the shape of the quick-change electrode head 1 can be replaced with a circular, square or elliptical structure according to needs, to adapt to different assembly models. The insertion design of the dovetail groove 5 can adapt to the copper plate 3 of the quick-change structure to complete the quick-change process. In the process of meeting the replacement conditions, the replacement process can be completed within one minute by directly using two simple operations of pushing out and pushing in. A quick-change copper plate is embedded on the dovetail groove. The surface of this copper plate is specially designed to avoid rubber and plastic. During welding, the quick-change copper plate will come into contact with the aluminum cover plate. After its service life reaches a certain number, which is about 2,000 times, there is also a risk of sticking to the aluminum cover plate. In this way, the copper plate is quickly replaced through a mechanical mechanism. The mechanism can achieve quick replacement within 1 minute, thereby increasing the life of the lower electrode head from the original 2,000 times to tens of thousands of times. Moreover, after verification, the quick-change copper plate is far more economical than grinding the lower electrode head.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the electrode head base 2 is longitudinally provided with a first plug hole 4 and a second plug hole 6 along the front and rear ends of the dovetail groove 5, and the first pole 8 and the second pole 7 are respectively inserted into the first plug hole 4 and the second plug hole 6. The design of the two groups of poles cooperates with the first plug hole 4 and the second plug hole 6 to complete the guide insertion process, so that the overall quick-change copper plate electrode assembly is formed.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the second plug hole 6 has a chamfered structure along the groove surface of the dovetail groove 5, and the chamfered structure is in guiding contact with the second pole 7, and the second pole 7 has a built-in ball structure in rolling contact with the plug end surface of the copper plate 3. In order to facilitate the installation of the second pole 7, the present application has a chamfered structure of the second plug hole 6 along the groove surface of the dovetail groove 5, which facilitates the second pole 7 to complete the guiding process of vertical insertion.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the volume of the first pole 8 is smaller than that of the second pole 7; wherein the small volume structure of the first pole 8 can reduce the pushing resistance and save the production cost.

[0026] The first plug hole 4 has a shallow groove structure along the outer end of the dovetail groove 5, and the shallow groove structure is in positioning and guiding contact with the first pole 8. The first plug hole 4 with the shallow groove structure can cooperate with the first pole 8 to complete the pushing process in the copper plate insertion process, and the design of the shallow groove structure can prevent the copper plate from being pushed out of the boundary during the copper plate insertion process.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the protruding end of the first pole 8 is provided with a chamfered structure, which is in a guiding contact structure with the first plug hole 4. The chamfered structure is adapted to the quick installation and quick replacement operation process.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a plug 9 is provided on the back of the copper plate 3, and the plug 9 is plugged and matched with the dovetail groove 5, and three groups of protrusion structures are retained on the front of the copper plate 3. Among them, the three groups of protrusion structures are suitable for welding and are convenient for grinding. Due to the three groups of protrusions, only the end faces of the three groups of protrusions need to be polished during the grinding process, and there is no need to grind the entire plane. It saves costs and reduces the difficulty of operation.

[0029] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
