[0017] A printing plate fixing edge magnetic block 6 is arranged on the side edge of the bottom surface of the printing mechanism 1, and the PCB bottom plate group 2 is composed of a printing bottom plate 7 and a bottom plate fixing clamp frame 8. The bottom plate fixing clamp frame 8 is arranged side by side on the edges of the upper and lower sides of the printing bottom plate 7. The bottom plate fixing clamp frame 8, the printing bottom plate 7, and the printing plate fixing edge magnetic block 6 are all made of magnetic materials. The printing bottom plate 7 is tightly attached to the bottom side of the printing mechanism 1, and the top side of the bottom plate fixing clamp frame 8 is adsorbed and fixed on the bottom side of the printing plate fixing edge magnetic block 6, and a printing slot 9 is arranged on the printing bottom plate 7.

[0018] The printing mechanism 1 is internally provided with an electronic control board 10, a tin paste box 11, and a printing head structure 12. The electronic control board 10 is arranged on the top side of the tin paste box 11. The printing head structure 12 is provided with a plurality of groups. The plurality of groups of printing head structures 12 are arranged at equal intervals on the bottom side of the printing mechanism 1, and the printing head structure 12 is electrically connected to the electronic control board 10. The top side of the printing head structure 12 is connected to the tin paste box 11. The power supply interface 4 is electrically connected to the electronic control board 10, and the bottom side of the tin paste supply interface 5 is connected to the tin paste box 11.

[0019] The print head structure 12 is composed of a tin paste delivery pipe 13, a structural shell 14, a high-sensitive thermal resistor 15, an inner valve core 16, and a valve core end magnetic block 17. The structural shell 14 is provided with a conical drip irrigation chamber 18 and a tin paste retaining chamber 19. The tin paste retaining chamber 19 is arranged on the top side of the conical drip irrigation chamber 18, and the top side of the conical drip irrigation chamber 18 is connected to the tin paste retaining chamber 19. The tin paste delivery pipe 13 is connected to the top side of the structural shell 14, and the tin paste The paste delivery pipe 13 is communicated with the tin paste retaining chamber 19, the high-sensitive thermal resistor 15 is arranged on the top side of the tin paste retaining chamber 19, the valve core end magnetic block 17 is arranged at the bottom end of the inner valve core 16, the inner valve core 16 is arranged in the conical drip irrigation chamber 18, and the inner valve core 16 can move up and down inside the conical drip irrigation chamber 18, the high-sensitive thermal resistor 15 is electrically connected to the electric control board 10, and the valve core end magnetic block 17 has the same magnetic pole as the top surface of the printing bottom plate 7.

[0020] The working principle of the utility model is as follows: the device is installed on a PCB board production station, and a printing slot 9 is etched on the printing base plate 7 in advance according to the PCB board to be processed, and the power supply interface 4 and the tin paste supply interface 5 of the equipment are connected to the corresponding supply. When a group of new PCB boards are transported to the bottom side of the printing mechanism 1 through the transportation mechanism, the printing mechanism will print the tin paste on the PCB board according to the printing slot 9 on the printing base plate 7.

[0021] During operation, the tin paste inside the tin paste box 11 is ensured to be sufficient, and the electric control board 10 provides power to the high-sensitive thermal resistor 15 to make the high-sensitive thermal resistor 15 heat up. After heating, the high-sensitive thermal resistor 15 heats the tin paste in the tin paste retaining chamber 19. The heated tin paste is pushed to drip from the bottom side of the conical drip irrigation chamber 18 due to its gravity and the pressure generated after the internal heat flow. The dripping tin paste passes through the printing slot 9 onto the PCB board. When there is no printing slot 9 on the bottom side of the printing head structure 12, the valve core end magnetic block 17 will produce a repulsive effect due to the magnetic pole set with the same pole as the printing bottom plate 7, pushing the inner valve core 16 to move upward. The inner valve core 16 is blocked between the conical drip irrigation chamber 18 and the tin paste retaining chamber 19, resulting in the tin paste being unable to drip downward due to the action of the heat flow pressure. When there is no printing bottom plate 7 on the bottom side of the inner valve core 16, the inner valve core 16 can fall directly without hindering the flow of the tin paste.

[0022] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
