[0002] Mobile phone, the full name is "handheld mobile phone", "handheld wireless telephone", "mobile phone handset", also known as mobile phone or wireless phone, usually referred to as "mobile phone". Common mobile phones include smart phones and feature phones. Smart phones refer to those with independent and open operating systems like personal computers, and most of them have large-size capacitive touch screens that are easy to operate. Smart phones include many components such as motherboards, cameras, batteries, screens, etc., which need to be fixed on the middle frame. The middle frame of the mobile phone is the main frame of the mobile phone. During the production and processing process, steel sheets need to be welded at the preset position of the middle frame of the mobile phone. The steel sheet is pre-processed into the specifications corresponding to the middle frame of the mobile phone. When welding the steel sheet, a fixed fixture is generally set on the workbench, and the middle frame of the mobile phone is placed on the fixed fixture for positioning. The traditional method is that the staff takes out the steel sheet of the corresponding specifications and sticks it on the predetermined welding position of the middle frame of the mobile phone, and then performs the welding operation. However, manual operation is inefficient and prone to deviations. In order to improve the working efficiency, welding equipment that can automatically perform welding operations has been adopted.
