In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features, which are used to distinguish and describe the features, without distinction of order or importance. In the description of the present utility model, unless otherwise specified, "multiple" means more than two.

[0032] In one embodiment of the present invention, Figure 1-3As shown, a high-safety butt welding machine includes a body 1, a control box 2, a driving device 3, an upper butt welding component 4, a lower butt welding component 5, a sensor 6 and a foot pedal 7; the body 1 is provided with a mounting seat 11 and a support seat 12, the mounting seat 11 is located above the support seat 12, the driving device 3 is installed on the mounting seat 11, the output end of the driving device 3 is connected to the upper butt welding component 4, the driving device 3 is used to drive the upper butt welding component 4 to move up and down; the lower butt welding component 5 is installed on the support seat 12, the lower butt welding component 5 is opposite to the upper butt welding component 4, the foot pedal 7 is arranged on the front side of the bottom of the body 1, the control box 2 is arranged on the side of the body 1, the control box 2 is electrically connected to the sensor 6 and the foot pedal 7 respectively, and the sensor 6 is used to detect whether a butt welding shell is placed on the lower butt welding component 5. In this embodiment, the driving device 3 is a cylinder, and the sensor 6 is a prior art. During installation, the driving device 3 is installed at the end of the mounting seat 11, and the output end of the driving device 3 is connected to the upper touch welding component 4, the lower touch welding component 5 is installed on the support seat 12, so that the lower touch welding component 5 is located directly below the upper touch welding component 4, the sensor 6 is installed on the right side of the lower touch welding component 5, the pedal 7 is installed on the front side of the bottom of the body 1, and the control box 2 is installed on The right side of the machine body 1, and the control box 2 is electrically connected to the foot pedal 7 and the sensor 6 respectively. It should be noted that the upper touch welding component 4 and the lower touch welding component 5 need to be powered on respectively. When working, the touch welding workpiece is placed on the lower touch welding component 5. At this time, the sensor 6 does not sense the obstruction of the touch welding shell above it. Therefore, even if the foot pedal 7 is stepped on at this time, the control box 2 will not transmit a signal to the drive device 3 to start working. After the touch welding workpiece is placed, the touch welding shell is placed on the lower touch welding component 5. When the butt welding shell covers the top surfaces of the two butt welding workpieces, and the butt welding shell covers the sensor 6, that is, the butt welding shell blocks the sensor 6, then the sensor 6 feeds back a signal to the control box 2, and then after stepping on the foot pedal 7, the driving device 2 can drive the upper butt welding component 4 downward until the upper butt welding component 4 contacts the butt welding shell. At this time, the upper butt welding component 4, the butt welding shell, the butt welding workpiece and the lower butt welding component 5 form a loop, so that the butt welding workpiece is welded to the butt welding shell; this application is passed through The machine body 1, the mounting base 11, the support base 12, the control box 2, the driving device 3, the upper butt welding component 4, the lower butt welding component 5, the sensor 6 and the pedal 7.
