[0041] Preferably, the angle-adjustable hot-press soldering head mechanism 100 further includes a temperature-sensing plug mounting block 96 and a temperature-sensing wire plug 97. The upper and lower ends of the temperature-sensing plug mounting block 96 are respectively fixedly mounted on the upper and lower edges of the mounting opening 11, and the temperature-sensing plug mounting block 96 is located on the inner side of the package end cover 12. The temperature-sensing plug mounting block 96 is provided with a receiving groove 961 on the side wall facing the package end cover 12, and the temperature-sensing wire plug 97 is fixedly mounted in the receiving groove 961. The package end cover 12 is provided with an observation hole 121 facing the temperature-sensing wire plug 97. The temperature-sensing wire plug 97 is electrically connected to the control system. The control system is provided with a display module (not shown), which is installed on the outer side wall of the mounting shell 10 and is used to display the pressure data of the pressure sensor 30 and the temperature data of the temperature-sensing wire plug 97. The display module can be a touch display screen or a CNC display screen.

[0042] When the angle-adjustable hot press solder head mechanism 100 is working, the fine-tuning nut 24 is rotated to drive the adjustment block 26 to move up and down, and then the pressure of the spring 22 on the upper pressure shaft 28 is adjusted, thereby adjusting the pressure of the upper pressure shaft 28 on the upper end of the pressure sensor 30. The pressure of the hot press welding piece 70 on the workpiece during welding is transmitted to the lower end of the pressure sensor 30 through the lower pressure shaft 40. The forces on the upper and lower ends of the pressure sensor 30 are equal and opposite. The pressure sensor 30 then transmits the data to the control system and displays it, and the staff directly adjusts the required pressure data. The front electrode heat sink 60 and the rear electrode heat sink 63 are respectively electrically connected to the two poles of the external welding heating circuit to form a heating circuit, so that the hot press welding piece 70 is heated and then the subsequent welding process is completed. When it is necessary to adjust the swing angle of the hot press welding piece 70, unscrew the four adjustment screws 54, and adjust the length of the two limit screws extending below the limit screw hole 516, so that the middle connecting block 52 rotates slightly around the rotating shaft 53 to the specified position, and then tighten the adjustment screw 54. The diameter of the adjusting through hole 512 is larger than the diameter of the screw body 542. Therefore, the screw body 542 has a certain swing in the adjusting through hole 512, and the middle connecting block 52 can be slightly rotated to fine-tune the angle, thereby fine-tuning the angle of the hot pressing welding sheet 70. At the same time, the axial position of the middle connecting block 52 relative to the lower pressing shaft connecting block 51 on the rotating shaft 53 can also be slightly adjusted.

[0043] refer to Figure 12 to Figure 14, which is different from the first embodiment, the rotating shaft 53 of the position adjustment component 50 is a spherical ball, and accordingly, the upper shaft groove 511 is a hemispherical shape that matches the shape and size of the top of the rotating shaft 53, and the lower shaft groove 521 is a hemispherical shape that matches the shape and size of the bottom of the rotating shaft 53. The number of the limiting screws is four, and accordingly, the number of the limiting screw holes 516 is also four. The four limiting screw holes 516 are respectively opened on the front, back, left, and right sides of the lower pressure shaft connecting block 51 on the rotating shaft 55. The four limiting screws are screwed and inserted into the limiting screw holes 516, and the lower ends of the limiting screws are against the top of the middle connecting block 52. When it is necessary to adjust the angle of the hot pressing welding sheet 70, unscrew the four adjusting screws 54, and adjust the length of the four limiting screws extending below the limiting screw holes 516, so that the middle connecting block 52 can be universally rotated around the rotating shaft 53 to a specified position, and then the adjusting screws 54 are screwed on and locked.

[0044] The middle connecting block of the angle-adjustable hot-press soldering head mechanism of the utility model can flexibly adjust the angle along the rotating shaft, so as to flexibly adjust the angular position of the hot-press soldering piece, which is more convenient to use; the heat sink connecting block not only plays the role of fixing and insulating the front and rear electrode heat sinks, but also can insulate and separate the front and rear electrode heat sinks from the middle connecting block, thereby ensuring the normal operation of the heating circuit and making the overall structure more compact and rigorous.

[0045] It should be noted that the number of the lower pressing shaft positioning slots provided at the bottom of the lower pressing shaft may be two, three or other numbers. The depth of the matching slot may be greater than the thickness of the partitioning protrusion; the height of the adjustment space may be flexibly set according to the angle amplitude that the hot pressing welding sheet needs to adjust. The front electrode heat sink and the rear electrode heat sink may be made of conductive materials such as gold, silver, brass or red copper.

[0046] The present invention is described above in conjunction with the best embodiment, but the present invention is not limited to the embodiment disclosed above, but should cover various modifications and equivalent combinations based on the essence of the embodiment.
