The front end of the main slider 9 extends downward to form a pry bar mounting portion for hingedly mounting a pry bar 11. The pry bar 11 is hingedly mounted on the pry bar mounting portion. When the pry bar does not rotate, the pry bar The upper end is fitted on the main slider to form an axial limit for the core shaft assembly.

When the main slider 9 moves downward, the sub-spring and the mother spring are compressed at the same time. The setting of the sub-spring and the mother spring enables the main slider and the spindle assembly to be separated at different operation stages.

[0032] In this embodiment, the belt transmission intermittent mechanism includes a driving pulley 18, a driven pulley 19, a base slider 21 and a sliding pulley 20 installed between the first base plate 1 and the second base plate 2. The sliding pulley 20 is rotatably installed on the base slider 21. There are three driven pulleys 19 and the three driven pulleys and the driving pulley are distributed in a rectangular shape on the inner side of the second base plate 2. The second base plate 2 is provided with a base slide groove for slidingly installing the base slider 21.

A driving pulley and a driven pulley are installed between two base plates with the same structure. The input transmission mechanism transmits power to the driving pulley 18, and the driving pulley 18 transmits power to the driven pulley through the belt. The four pulleys are distributed in a rectangular shape on the second base plate 2. The base slider 21 slides along the base slide groove on the base plate in the vertical direction. After the base slider 21 slides down, the sliding pulley 20 cooperates with the belt for transmission, and power transmission can be realized.

[0033] In this embodiment, a main positioning block is fixedly connected to the base slider 21, and a positioning ring 151 (such as Figure 5 As shown in the figure, the main positioning block is fixedly installed with the main slider 9, and the positioning ring is embedded in the main slider 9.

[0034] In this embodiment, the electric soldering iron mechanism includes a soldering base plate 211, a soldering wire guide roller assembly 25 installed on the outside of the soldering base plate 211, a soldering gun 24, and a soldering gear assembly 26 installed on the inside of the soldering base plate 211; the sliding pulley 20 cooperates with the belt to transmit power to the soldering gear assembly 26, and the soldering gear assembly 26 drives the soldering wire guide roller assembly to rotate 25. Figure 6 Figure 7 As shown, a welding wire guide roller assembly 25 for conveying the welding wire is installed on the outer side of the welding substrate 211, and a welding gear assembly 26 is installed on the inner side of the welding substrate 211. The welding gear assembly includes a welding active gear coaxially arranged with the sliding pulley 20 and a welding driven gear group meshing with the welding active gear. A welding wire mounting wheel 23 for mounting the welding wire and a welding wire guide hook 22 arranged below the welding wire mounting wheel 23 are provided on the welding substrate 211. The first base plate 1 is also provided with a base slide groove and a base slide block 21. The base slide block 21 is coaxially arranged with the sliding pulley 20 and the welding driving gear. The rotation of the sliding pulley 20 drives the welding driving gear to rotate, and the rotation of the welding driving gear drives the welding driven gear group to rotate. A part of the welding driven gear group is coaxially arranged with the welding wire guide roller assembly 25. The rotation of the welding driven gear group drives the welding wire guide roller assembly 25 to rotate. The welding wire is installed on the welding wire installation wheel 23. The welding wire installation wheel 23 passes through the welding wire guide hook 22 and feeds downward through the welding wire guide roller assembly 25, and finally cooperates with the welding gun 24.

[0035] In this embodiment, the input transmission mechanism includes an input wheel 15 installed on the outer side of the first base plate, an input driving tooth 16 coaxially arranged with the input wheel 15 (i.e., the shaft 3), and an input driven gear set 17 meshing with the input driving tooth 16. The input driven gear set 17 transmits the input power to the belt transmission intermittent mechanism; the crank slider mechanism includes a crank connecting rod 4 coaxially installed with the input wheel, a crank slider 41 installed at the end of the crank connecting rod 4, and a pressure claw plate 42 fixedly connected and installed with the crank slider 41. The rotation of the input wheel 15 drives the crank connecting rod to move and drive the crank slider 41 to move in the vertical direction. The crank slider 41 drives the pressure claw plate 42 to drive the main slider 9 to slide in the set direction. The gear at the lower end of the driven gear set 17 is coaxially arranged with the driving pulley 18. The rotation of the input wheel 15 drives the driven gear set 17 to rotate, thereby rotating the driving pulley 18. At the same time, the rotation of the input wheel 15 also drives the crank slider mechanism to move, thereby causing the vertical motion intermittent mechanism to move.

[0036] Organization operation process:

[0037] The first downward movement of the crank slider:

[0038] Before the operation starts, the crank slider has no contact with the main slider; when the operation starts, the input wheel 15 is rotated, the crank slider mechanism starts to operate, the crank slider 41 and the pressure claw plate 42 move downward and drive the main slider 9 to move downward, the crank slider mechanism moves downward to the lower limit position and starts to return, at this time the horizontal slider 10 moves along the closed ring groove to the first slope surface 82 and rebounds to the lower end of the strip baffle 81 (the lower end of the strip baffle 81 is provided with a baffle groove), the crank slider mechanism starts to return and move upward, at this time, the sliding pulley 20 is in contact with the belt for transmission, the parent-child spring is compressed at the lower end, the pry bar 11 slides downward along the inner wall of the conical limit guide cylinder 14 and forms a lever structure, and the upper end of the pry bar 11 rotates and releases the axial limit on the spindle assembly.

[0039] The first upward movement of the crank slider:

[0040] When the input wheel 15 continues to rotate, the crank slider starts to move upward. At this time, the horizontal slider 10 is restricted due to the setting of the first slope surface 82, and the main slider cannot move. The sliding pulley 20 rotates to drive the electric soldering iron mechanism on the first base plate 1 to operate.

[0041] The second downward movement of the crank slider:

[0042] The input wheel 15 continues to rotate, the crank slider mechanism moves downward and contacts the main slider 9 , and after contacting the main slider, the crank slider mechanism continues to push the main slider 9 downward, and the horizontal slider 10 moves downward with the main slider 9 and contacts the second slope surface 83 .

[0043] The second crank slider moves upward:

[0044] Continue to rotate the input wheel 15, the crank slider mechanism moves upward, and the horizontal slider 10 rebounds after touching the second inclined surface 83 and starts to move upward. Since the horizontal slider 10 moves inward in the closed ring groove, the horizontal slider 10 drives the core shaft limiting piece 6 to move inward to unlock the core shaft assembly. Since the pry bar 11 has been rotated to unlock when moving downward, the core shaft 7 will be bounced upward and limited by the axial limiting ejector pin 5 due to the action of the sub-spring 27; due to the action of the parent spring 28, the horizontal slider 10 moves upward along the closed ring groove to the position of the third inclined surface 84 and is rebounded to the initial position. At this time, the pry bar 11 returns to the initial position to limit the core shaft 7, and the core shaft limiting piece 6 also returns to the initial position to limit the core shaft 7. At the same time, the belt drive intermittent mechanism will also return to the initial position. During the upward movement of the belt drive intermittent mechanism, the electric soldering iron mechanism has no power input, and the welding wire will not be fed.
