[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3 The utility model provides a technical solution: a cup-type air pressure tinning device, including a fixed plate 7, two sensing components 6 are respectively provided on the surface of the fixed plate 7, and the two sensing components 6 are respectively installed on the left and right surfaces of the fixed plate 7 at different heights. The fixed plate 7 is fixedly connected to the external printing equipment body.

[0020] A cup holder 9 is fixedly installed on the lower end of the fixed plate 7, and a piston 8 is fixedly installed in the inner cavity of the cup holder 9 by screws. A discharge port for the solder paste to flow out is provided on the piston 8. An opening is provided at the bottom of the cup holder 9, and the piston 8 is connected to the opening. A rubber sealing ring 5 is fixedly installed on the port of the piston 8. The inner wall of the cup holder 9 is threadedly sleeved with a transparent cup body 3, and the top of the transparent cup body 3 is threadedly sleeved with a cup cover 2. The top of the cup cover 2 is fixedly connected with a quick-connect connector 1, and the inner cavity of the transparent cup body 3 is slidably sleeved with a solder paste tank 4. A cavity is provided inside the transparent cup body 3 for installing the solder paste tank 4. The solder paste tank 4 and the rubber sealing ring 5 are slidably sleeved with each other, and the solder paste tank 4 is put on the piston 8 with the opening facing downward. The rubber sealing ring 5 installed on the piston 8 is close to the inner wall of the solder paste tank 4, which plays a sealing role to prevent the solder paste from leaking out from the edge of the solder paste tank 4.

[0021] The air pressure tinning device adopts the air pressure extrusion method. In addition to the air pressure method, the extrusion can also be performed by using a cylinder or a motor to drive a screw rod as a power.

[0022] When in use, first install the fixing plate 7 on the printing equipment body, then thread the cup cover 2 onto the transparent cup body 3, and connect the quick-insert connector 1 to the cup cover 2 and the inside of the transparent cup body 3, as well as the discharge port on the piston 8 and the opening on the cup base 9 to the outside atmosphere. The solder paste is stored in the solder paste tank 4, and the solder paste tank 4 is placed on the piston 8 with the opening facing downward. The rubber sealing ring 5 installed on the piston 8 is tightly attached to the inner wall of the solder paste tank 4 to seal and prevent the solder paste from leaking out from the edge of the solder paste tank 4. The discharge port on the piston 8 is The solder paste tank 4 is blocked, and then a sealed space is formed through the space inside the transparent cup body 3, and is slidably sleeved on the solder paste tank 4, and the transparent cup body 3 is threadedly connected to the cup seat 9, and the solder paste in the solder paste tank 4 is communicated with the external atmosphere through the discharge port on the piston 8 and the opening on the cup seat 9, that is, the piston 8 and the cup seat 9 are communicated with each other, and are connected to the external air path with the quick plug connector 1, and the air is ventilated to the inside of the transparent cup body 3 through the quick plug connector 1 to increase the air pressure in the internal sealed space. The air pressure inside the transparent cup body 3 is higher than the external atmospheric pressure, and the internal air is used to ventilate the transparent cup body 3. The pressure is used as the driving force to push the solder paste tank 4 downward along the piston 8, thereby squeezing out the solder paste in the solder paste tank 4. The inside of the transparent cup body 3 is evacuated through the quick-connect connector 1 to reduce the air pressure in the internal sealed space. The air pressure inside the transparent cup body 3 is lower than the external atmospheric pressure. The external atmospheric pressure is used as the driving force to push the solder paste tank 4 upward along the piston 8 to achieve the function of stopping the addition of solder. The sensing component 6 includes two sensors. The two sensors are mounted on the fixing plate 7. There is a certain height difference between the two sensors. The sensing component 6 can sense the solder paste tank 4 through the transparent cup body 3. When the solder paste in the solder paste tank 4 is sufficient, both sensors can sense the solder paste tank 4. At this time, the printing equipment is in normal working condition and there is no alarm prompt. As the solder paste is consumed, the solder paste tank 4 descends along the piston 8. When the higher sensor can no longer sense the solder paste tank 4, but the lower sensor can sense the solder paste tank 4, the equipment alarm reminds that the solder paste content in the solder paste tank 4 is insufficient. When the solder paste is exhausted, both sensors can no longer sense the solder paste tank 4, the equipment stops working, and a new solder paste tank 4 needs to be replaced.
