Description

Technical Field

[0001] The utility model relates to the technical field of automobile welding equipment, in particular to an electrode cap replacement device. Background Art

[0002] The electrode cap is a type of welding electrode used for welding of resistance welding equipment, such as fixed spot welding machines, hanging spot welding machines and manipulator spot welding machines. Because it is placed on the electrode connecting rod, it is called an electrode cap. The material is mostly chromium zirconium copper, and there is also dispersed copper. After a certain number of welding times (usually 1000-1200 points), it needs to be repaired or replaced due to wear and tear, and is a welding consumable part.

[0003] With the innovative development of science and technology, intelligence has been popularized in all fields of the automotive manufacturing industry. The most widely used in the automotive manufacturing industry is the welding robot. However, the electrode cap of the welding robot needs to be replaced after a certain number of uses. However, the replacement of the electrode cap still needs to be replaced manually one by one. The replacement process is cumbersome and time-consuming, which can easily affect the production progress and efficiency. If the operation is improper, it is easy to cause the electrode cap to be installed unstable, thereby reducing the welding quality and stability. In view of the above problems, an electrode cap replacement device is proposed to solve them. Utility Model Content
