[0002] Bottom fill glue is simply the glue for bottom filling. The general definition is that it uses chemical glue (the main component is epoxy resin) to fill the bottom of the BGA package mode chip. It uses heated curing to fill a large area of ​​the BGA bottom gap (generally covering more than 80%), so as to achieve the purpose of reinforcement and enhance the drop resistance between the BGA package mode chip and PCBA. Therefore, this type of glue is widely used, and factories need to produce a large number of them to meet market demand. During production, factories need to use a series of production equipment, including stirring equipment, storage equipment, etc.

[0030] The heat insulation pad 2 is arranged outside the barrel body 1, which can protect the staff and prevent the staff from being scalded by excessive temperature on the outer surface of the barrel body 1. The barrel body 1 is made of heat-conducting material; the water source in the chamber 3 can be discharged, and the water source in the chamber 3 can be discharged by opening the control valve at the water outlet pipe 6. The water source in the chamber 3 is lower than the position of the air outlet pipe 8, which prevents the water source from flowing out of the air outlet pipe 8. One end of the connecting pipe 11 is connected to the inside of the air outlet pipe 8. The hot air in the chamber 3 is transported to the inside of the barrel body 1 through the connecting pipe 11, so that the temperature of the bottom filling glue in the barrel body 1 is evenly heated, and the temperature heating adjustment method is simple and convenient;

[0031] See also Figure 4 The stirring connection assembly 14 is located inside the barrel body 1. The stirring connection assembly 14 includes a mounting cylinder 141 mounted on the power driving end of the motor 13. A groove 142 is provided inside the mounting cylinder 141. Two symmetrical limiting grooves 143 are provided inside the groove 142. A first threaded hole 144 is provided inside the mounting cylinder 141. A connecting rod 145 is connected inside the groove 142. Two symmetrical limiting plates 146 are installed on the top of the connecting rod 145. The limiting plate 146 is located inside the limiting groove 143. A second threaded hole 147 is provided inside the limiting plate 146. A bolt 148 is connected to the inside of the second threaded hole 147 and the first threaded hole 144. A butterfly handle 149 is installed at one end of the bolt 148. A plurality of stirring plates 1410 are installed outside the connecting rod 145.

[0032] When the limiting plate 146 is located inside the limiting groove 143, the positions of the second threaded hole 147 and the first threaded hole 144 correspond to each other, so that the bolt 148 can be connected to the inside of the first threaded hole 144 and the second threaded hole 147. The butterfly handle 149 is convenient for the staff to hold the butterfly handle 149 and rotate it.

[0033] The implementation principle of this embodiment is as follows: the bottom filling glue is transported from the feed pipe 15 to the inside of the barrel body 1, and then the control valve at the water inlet pipe 5 is opened and the control valve at the water outlet pipe 6 is closed, and the water source is transported from the inside of the water inlet pipe 5 to the inside of the chamber 3. After the water source is transported, the control valve at the water inlet pipe 5 is closed, and then the heating pipe 4 is started. The heating pipe 4 heats the water source in the chamber 3. Since the barrel body 1 is made of heat-conducting material, the barrel body 1 can be fully heated when the water source in the chamber 3 is heated. The heat insulation pad 2 is located outside the barrel body 1 to prevent the staff from being scalded. The hot air in the chamber 3 is transported to the inside of the barrel body 1 through the connecting pipe 11 connected to the air outlet pipe 8. At this time, there is heat inside and outside the barrel body 1, so that the temperature of the bottom filling glue in the barrel body 1 is evenly heated, and then the motor 13 is started. The motor 13 drives the stirring connection assembly 14 to rotate, so that the bottom filling glue in the barrel body 1 is evenly heated, and then the control valve at the discharge pipe 7 is opened to discharge the bottom filling glue in the barrel body 1.

[0034] When the stirring plate 1410 needs to be disassembled after long-term use, the user removes the barrel cover 9 from the top of the barrel body 1, and then rotates the bolt 148 while holding the butterfly handle 149 to disengage the bolt 148 from the second threaded hole 147 and the first threaded hole 144, and then removes the connecting rod 145 from the inside of the groove 142. At this time, the connecting rod 145 and the stirring plate 1410 are disassembled; when subsequently installing the connecting rod 145 with the mounting tube 141, the user positions the connecting rod 145 inside the groove 142, and the limiting plate 146 inside the limiting groove 143. At this time, the user connects the bolt 148 to the inside of the second threaded hole 147 and the first threaded hole 144 while holding the butterfly handle 149, and the connecting rod 145 can be fixed inside the mounting tube 141.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
