The servo motor 11 is of model SMBL-60P, and the output shaft of the servo motor 11 is fastened to the rotating shaft 12.

[0025] Two mounting blocks 4 are fixedly connected to the upper side of the processing base 2. A through T-slot 5 is opened on one side of each of the two mounting blocks 4. A guide plate 6 is slidably connected inside each of the two T-slots 5. A rack 7 is fixedly connected between the two guide plates 6. The rack 7 and the gear 13 mesh with each other. A horizontal plate 8 is fixedly connected to the upper side of the rack 7. Two support plates 14 are fixedly connected to the upper side of the horizontal plate 8. A placement platform 15 is fixedly connected to one side of the two support plates 14. A top plate 16 is fixedly connected to the upper side of the placement platform 15. A circuit board body 17 is arranged on the upper side of the top plate 16. The resin filling device can operate continuously, avoiding the tediousness of frequent manual operation, saving time and manpower, and making the processing more efficient.

[0026] Both ends of the horizontal plate 8 are fixedly connected to side plates 21. A double-ended lead screw 22 is rotatably connected between the two side plates 21. Two lead screw sleeves 30 adapted to the double-ended lead screw 22 are provided on the double-ended lead screw 22. A fixing plate 25 is fixedly connected to one side of each of the two lead screw sleeves 30. A reinforcing plate 26 is fixedly connected to one side of each of the two fixing plates 25. A rubber pad 27 that fits against the circuit board body 17 is fixedly connected to one side of each of the two reinforcing plates 26.

[0027] An L-shaped vertical plate 31 is fixedly connected to the upper side of the processing base 2. An array of guide rods 32 are slidably connected to one side of the L-shaped vertical plate 31. A mounting base 33 is fixedly connected to the lower side of the guide rods 32. A connecting spring 35 is arrayed between the mounting base 33 and the L-shaped vertical plate 31. A scraper 34 is fixedly connected to the lower side of the mounting base 33. The upper side of the guide rods 32 passes through the L-shaped vertical plate 31 and extends to the other side of the L-shaped vertical plate 31. A fixing block 36 is fixedly connected to the upper side of the guide rods 32. An L-shaped plate 37 is fixedly connected to the upper side of the L-shaped vertical plate 31. A bolt 9 is threadedly connected to one side of the L-shaped plate 37. The lower side of the bolt 9 passes through the L-shaped plate 37 and extends to the other side of the L-shaped plate 37.

[0028] Two symmetrically arranged L-shaped baffles 28 are fixedly connected to the upper side of the horizontal plate 8. A collection box 29 is snapped between the two L-shaped baffles 28. The collection box 29 is located below the placement platform 15. With the installation and use of the placement platform 15 and the top plate 16, the scraped items scraped off by the scraper 34 slide down from the placement platform 15 and the top plate 16 and finally fall into the collection box 29 for storage.

[0029] A mounting bracket 18 is fixedly connected to the upper side of the processing base 2. A resin filling device body 19 is fixedly connected to one side of the mounting bracket 18. A filling head 20 is fixedly connected to the lower side of the resin filling device body 19. The resin filling device body 19 adopts vacuum-assisted injection technology to fill the plug holes of the circuit board with resin in a vacuum environment. The pressure difference ensures that the resin is filled without air bubbles.

[0030] A limiting rod 23 is fixedly connected between the two side plates 21. The inside of the lead screw sleeve 30 is slidably placed on the outer surface of the limiting rod 23. The limiting rod 23 can limit the movement trajectory of the two lead screw sleeves 30 so that the two rubber pads 27 can move smoothly to clamp the circuit board. At the same time, it can also avoid damaging the circuit board and better protect the circuit board. One side of the double-ended lead screw 22 passes through the side plate 21 and extends to one side of the side plate 21. A handwheel 24 is fixedly connected to one side of the double-ended lead screw 22.

[0031] The working principle of the circuit board resin filling device provided by this utility model is as follows:

[0032] By starting the servo motor 11, the output shaft of the servo motor 11 can drive the gear 13 at the rotating shaft 12 to rotate continuously. In this way, the gear 13 can drive the rack 7 to move and adjust. At this time, the two guide plates 6 at the rack 7 can move inside the T-slots 5 of the two mounting blocks 4 to limit the movement trajectory of the rack 7. Then, as the rack 7 moves, all the circuit board bodies 17 can be transported to the bottom of the resin filling device body 19 in sequence. Then, the filling head 20 of the resin filling device body 19 fills the plug holes of the circuit board with resin. In this way, the circuit board resin filling device can continuously perform resin filling operations on all the circuit boards until all filling tasks are completed. The processing is time-saving and labor-saving, and the processing efficiency of the circuit board resin filling device is improved.

[0033] By sequentially placing all the circuit board bodies 17 above the top plate 16, and then turning the handwheel 24, the handwheel 24 drives the double-ended lead screw 22 to rotate. This allows the two lead screw sleeves 30 on the double-ended lead screw 22 to move towards each other, enabling the two lead screw sleeves 30 to drive the two rubber pads 27 to clamp the two ends of the circuit board, thus positioning the circuit board and facilitating stable and reliable resin filling. Next, the bolt 9 is tightened, causing the bolt 9 to move downwards and press against the fixing block 36. This compresses the elastic scraper 34, adjusting it to the same height as the circuit board body 17. As the resin-filled circuit board moves towards the scraper 34, the scraper 34 automatically scrapes away excess resin from the circuit board, resulting in more uniform resin filling on the circuit board, enhancing the filling effect, and improving the processing quality of the circuit board resin filling device.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
