[0002] During the processing of glasses, the instructions need to be attached by welding. Figure 1 The hinge blocks are respectively welded to the temples and the frame, and then the two hinge blocks are connected through a hinge axis to realize the connection between the temples and the frame.

[0003] In the prior art, in order to make the welding between the hinge block and the temple more convenient, a welding machine has appeared, including a machine platform, a temple mounting seat, a heating tube and a clamp are arranged on the machine platform, and a foot pedal A for controlling the lifting and lowering of the clamp and a foot pedal B for controlling the operation of the heating tube. When welding, the hinge block is manually mounted on the clamp, and then the temple is placed on the temple mounting seat, the foot pedal A is started to drive the clamp to descend, and the foot pedal B is started to control the heating of the heating tube, thereby completing the welding between the hinge block and the temple. However, this welding is not convenient enough when controlled by the foot pedal, and it is not easy to control the lifting and lowering of the clamp and the heating time of the heating tube, resulting in unqualified welding between the temple and the hinge block, and the heating time of the heating tube is controlled by the foot pedal, which requires very skilled staff to accurately grasp. Whether the time is too short or too long, the hinge block processing will be unqualified, so the requirements for the staff are very high. At the same time, the clamp collides with the temple mounting seat when it descends, which will wear the clamp and cause damage to the clamp. Summary of the invention

When working, the controller controls the solenoid valve to open, the cylinder starts to take in and out air, and the cylinder output shaft is extended or retracted. The controller controls the solenoid valve to close, cuts off the air intake and outlet of the cylinder, and the cylinder stops working. When the displacement sensor A senses the output shaft of the cylinder, it sends a signal to the controller through the sensing joint A, and the output shaft of the cylinder can be controlled to stop. When the displacement sensor B senses the output shaft of the cylinder, it sends a signal to the controller through the sensing joint B, and the output shaft of the cylinder can be controlled to stop.
