[0018] During implementation, the servo motor 22 drives the screw rod 23 to rotate, and the rotation of the screw rod 23 will cooperate with the thread of the feed nut block 24 to make it move up and down along the module frame 21.

[0019] Furthermore, if Figure 2 as well as Figure 3 As shown, a stroke sensing mechanism 4 is provided on one side of the Z-axis mechanism 2, and the stroke sensing mechanism 4 is used for stroke sensing when the feed nut block 24 moves. The stroke sensing mechanism 4 includes a support frame 41, a fixing plate 42, a photoelectric switch 43 and a sensing plate 44. The support frame 41 is fixedly connected to the surface of the module frame 21 by bolts, and the upper and lower ends of the support frame 41 are fixed with fixing plates 42 by bolts, and the surface of the fixing plate 42 is fixed with photoelectric switches 43 by screws, and the sensing plate 44 is fixed to the surface of the feed nut block 24 by screws, and the sensing plate 44 and the photoelectric switch 43 cooperate with each other for stroke sensing.

[0020] During implementation, the sensing sheet 44 and the photoelectric switch 43 are inductively coupled to each other to realize the sensing work of the stroke, and the anti-collision column 25 is used to prevent collision during movement.

[0021] Furthermore, if Figure 2 as well as Figure 3 As shown, the surface of the feed nut block 24 is connected with a fine-tuning mechanism 3, which is used for adjustment work during lifting and lowering. The fine-tuning mechanism 3 is composed of a fine-tuning seat 31, a slide rail 32, a slider 33 and an electric iron fixing bolt 35. The fine-tuning seat 31 is fixedly connected to the surface of the feed nut block 24 by bolts, and the surface of the fine-tuning seat 31 is installed with a slide rail 32 by screws, and the surface of the slide rail 32 is slidably connected with the slider 33; the surface of the slider 33 is fixedly connected to the electric iron connecting seat 34 by bolts, and the surface of the electric iron connecting seat 34 is threadedly connected with two groups of electric iron fixing bolts 35, which facilitate the fixing of the electric iron, and at the same time, a support plate is fixed on the surface of the fine-tuning seat 31 and located above the electric iron connecting seat 34, and a pressure sensor is fixed on the support plate, and the bottom end of the pressure sensor is fixedly connected to the surface of the electric iron connecting seat 34.

[0022] During implementation, since a support plate will be installed on the surface of the fine-tuning seat 31, a pressure sensor will be fixed between the support plate and the electric iron connecting seat 34.

When lifting, the servo motor 22 drives the screw rod 23 to rotate. The rotation of the screw rod 23 will cooperate with the thread of the feed nut block 24 to make it lift and lower along the module frame 21. At the same time, the stroke sensing mechanism 4 is used for stroke sensing during movement. When the stroke sensing mechanism 4 is implemented, the induction sheet 44 and the photoelectric switch 43 are mutually sensed to realize the stroke sensing work. The anti-collision column 25 is used for anti-collision during movement, thereby improving the safety of the lifting mechanism during movement and extending the service life of the lifting mechanism.

[0024] The lifting mechanism fine-tunes the electric iron through the fine-tuning mechanism 3. When the fine-tuning mechanism 3 is implemented, a support plate will be installed on the surface of the fine-tuning seat 31, and a pressure sensor will be fixed between the support plate and the electric iron connecting seat 34. The pressure sensor detects the pressure between the electric iron and the welding point. To ensure that the welding pressure is consistent every time, the pressure sensor is used for detection, and the slider 33 and the slide rail 32 slide against each other to make the electric iron connecting seat 34 connected to the bottom of the pressure sensor move up and down, so that the Z-axis mechanism 2 drives the electric iron on the surface of the electric iron connecting seat 34 to be fine-tuned up and down to ensure consistent pressure, thereby realizing the fine-tuning work of the lifting mechanism during lifting and lowering, and expanding the scope of use of the lifting mechanism.
