Description

Technical Field

[0001] This utility model relates to the technical field of solder paste packaging equipment, and in particular to a solder paste filling device. Background Technology

[0002] With the rapid development of electronic devices towards miniaturization, high density, and multifunctionality, surface mount technology (SMT) has become a core process in modern electronics manufacturing. In the SMT process, solder paste, as a crucial medium connecting electronic components to printed circuit boards, directly determines soldering quality, product reliability, and production efficiency. Solder paste needs to be precisely printed on micron-level pads and form a stable intermetallic compound (IMC) during high-temperature reflow to ensure electrical connectivity and mechanical strength.

[0003] Currently, after solder paste is produced, it needs to be filled into solder paste boxes for convenient storage, transportation, and sales. Filling machines are generally used for this purpose. When filling solder paste, a conveyor belt transports the solder paste box to the filling machine, stops moving once the box is below the filling device, and then the filling device injects the solder paste into the box. However, if the solder paste box is not positioned precisely on the conveyor belt, misalignment between the box and the filling device can occur, leading to leakage. Utility Model Content

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] This utility model discloses a solder paste filling device, such as... Figure 1-4 As shown, the system includes a machine body 1, on which a conveyor belt 2 is installed. The conveyor belt 2 is used to transport solder paste boxes. Baffles 21 are fixedly installed on opposite sides of the conveyor belt 2 to prevent the solder paste boxes from falling off the conveyor belt 2. A filling device 3 is also installed on the machine body 1. The filling device 3 has a discharge port located above the conveyor belt 2. The filling device 3 is connected to a conveying pipe, one end of which is connected to a container for solder paste. A rotary pump is connected between the conveying pipe and the container. When solder paste is being poured into the solder paste box, the rotary pump operates, delivering solder paste to the filling device 3 through the conveying pipe. The solder paste is then injected into the solder paste box from the discharge port. After filling is complete, the rotary pump stops operating, while the conveyor belt 2 continues to operate, transporting the solder paste box to the next process. Furthermore, the number of filling devices 3 is set to three, and the three filling devices 3 are arranged at intervals along the conveying direction of the conveyor belt 2. The three filling devices 3 can fill the solder paste into the three solder paste boxes at one time, which is more efficient.

[0023] In addition, pusher cylinders 4 are provided on both sides of the conveyor belt 2. The pusher cylinders 4 are horizontally arranged along the conveying direction perpendicular to the conveyor belt 2. A pusher plate 41 is fixedly installed on the piston rod of the pusher cylinder 4. The machine body 1 is provided with a driving component to drive the pusher cylinders 4 to move along the conveying direction of the conveyor belt 2. Specifically, the driving component includes a drive cylinder 5 fixedly installed on the machine body 1 along the conveying direction of the conveyor belt 2. A slider 51 is slidably connected to the machine body 1. The piston rod of the drive cylinder 5 is fixedly connected to the slider 51. The pusher cylinder 4 is fixedly installed on the slider 51. When the conveyor belt 2 conveys the solder paste box... After reaching the baffle 21, the conveyor belt 2 stops working. Then, the piston rod of the pusher cylinder 4 extends, driving the pusher plate 41 to insert between the three solder paste boxes and the other solder paste boxes. Then, the piston rod of the drive cylinder 5 extends, driving the pusher plate 41 to move closer to the pourer 3. The pusher plate 41 pushes the three solder paste boxes under the pourer 3 at a time, which makes the solder paste boxes and the pourer 3 better aligned. After the solder paste is poured, the conveyor belt 2 moves again to transport the solder paste boxes away. At the same time, another pusher plate 41 pushes the next batch of empty solder paste boxes, which is more efficient.

[0024] Additionally, a guide post 11 is fixedly installed vertically on the body 1, and a lifting seat 12 is slidably connected to the guide post 11. The filling device 3 is fixedly installed on the lifting seat 12. A lifting cylinder 13 is fixedly installed vertically on the body 1, and the piston rod of the lifting cylinder 13 is fixedly connected to the lifting seat 12. When the solder paste box is delivered to the area below the filling device 3, the piston rod of the lifting cylinder 13 retracts, causing the lifting seat 12 to descend, thus bringing the filling device 3 closer to the solder paste box. Furthermore, a limit plate 111 is fixedly installed at the top of the guide post 11. Additionally, a movable cylinder 14 is fixedly installed on the machine body 1. The movable cylinder 14 is positioned perpendicular to the conveying direction of the conveyor belt 2. A cutter 141 is fixedly installed on the piston rod of the movable cylinder 14. The cutter 141 is located below the filling device 3. The movable cylinder 14 drives the cutter 141 to move towards or away from the filling device 3. After the filling device 3 has filled with solder paste, due to the high viscosity of the solder paste, solder paste lines are prone to sticking between the filling device 3 and the solder paste box. When the solder paste box is transported, these lines easily adhere to the surface of the solder paste box. The piston rod of the movable cylinder 14 extends, driving the cutter 141 to move between the filling device 3 and the solder paste box to cut the solder paste lines. Furthermore, the cutter 141 is made of Teflon, which has high lubricity and does not easily cause solder paste to stick.

[0025] The implementation principle of the solder paste filling device in this embodiment of the utility model is as follows: When the conveyor belt 2 conveys the solder paste box to the baffle 21, the conveyor belt 2 stops working. Then, the piston rod of the pusher cylinder 4 extends, driving the pusher plate 41 to insert between the three solder paste boxes and other solder paste boxes. Then, the piston rod of the drive cylinder 5 extends, driving the pusher plate 41 to move closer to the filling device 3. The pusher plate 41 pushes the three solder paste boxes under the filling device 3 at one time, which can make the solder paste boxes and the filling device 3 better aligned. After the solder paste filling is completed, the conveyor belt 2 moves again to transport the solder paste boxes away.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
