[0017] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] Example 1: Key reference Figure 1-5 The device mainly includes a mounting back plate 1, a base plate 5, a support plate 6, a motor 7, a circular sleeve 10, and a glue bottle 12.

[0019] Support plates 6 are fixedly connected to both sides of the bottom of the base plate 5. A mounting back plate 1 is fixedly installed on the back of the base plate 5.

[0020] A glue box 2 is fixedly installed on the front of the mounting back plate 1 near the top. A discharge pipe 32 is connected to the side of the glue box 2 near the bottom. A connecting hose 31 is connected to the side of the discharge pipe 32 away from the glue box 2. A rigid pipe 14 is connected to the side of the connecting hose 31 away from the discharge pipe 32. The rigid pipe 14 is vertical.

[0021] An electric telescopic rod 3 is fixedly installed on the mounting back plate 1. A mounting base 29 is fixedly installed at the telescopic end of the electric telescopic rod 3. The mounting base 29 is slidably connected to the second limiting groove 30 of the mounting back plate 1 at its upper and lower limits. A rigid pipe 14 is fixedly installed on the mounting base 29. An electric valve 28 is fixedly installed on the rigid pipe 14. A limiting sleeve 4 is fixedly installed on the mounting back plate 1, and the rigid pipe 14 is slidably connected to the limiting sleeve 4.

[0022] The base plate 5 is rotatably connected to a rotating column 9. A disc 8 is fixedly connected to the top of the rotating column 9. Multiple circular sleeves 10 are distributed around the outer periphery of the top of the disc 8. A weighing sensor 11 is installed at the bottom of the inner side of the circular sleeve 10. A plastic bottle 12 is placed inside the circular sleeve 10 and presses on the weighing sensor 11.

[0023] A support plate 6 is fixedly installed at the bottom of the base plate 5, and a motor 7 is fixedly installed at the bottom of the base plate 5. The power output end of the motor 7 is connected to the rotating column 9.

[0024] A PLC controller (not shown in the figure) is also installed on the mounting backplate 1. The PLC controller is electrically connected to the electric valve 28, the weighing sensor 11, and the motor 7. When the motor 7 rotates the corresponding glue bottle 12 to the bottom of the rigid pipe 14, the weighing sensor 11 at the bottom of the corresponding glue bottle 12 detects the preset weight and closes the electric valve 28, thus stopping the flow of electronic encapsulation adhesive in the rigid pipe 14. This causes each glue bottle 12 to move to the bottom of the rigid pipe 14, allowing each glue bottle 12 to be filled with the preset weight of electronic encapsulation adhesive.

[0025] Example 2: Based on Example 1, a technical means was added to facilitate the protection of the bottom outlet of the rigid pipe 14.

[0026] Key reference Figure 3-5 This embodiment also includes a mounting box 13, a fixing plate 23, a first connecting plate 24, a hinge rod 20, and a sealing slide plate 17.

[0027] The mounting box 13 is a box with an open bottom, and it is fixedly mounted on the mounting back plate 1.

[0028] The top of the mounting box 13 has a first limiting groove 15, through which the rigid pipe 14 passes. Fixing plates 23 are fixedly installed on both sides of the rigid pipe 14. First connecting plates 24 are installed on the sides of the two fixing plates 23 that are far apart from each other. Two sealing slide plates 17 are slidably connected to the bottom of the mounting box 13. Extension blocks 18 are fixedly connected to the top of each of the two sealing slide plates 17. Hinge rods 20 are hinged between each of the two extension blocks 18 and the two first connecting plates 24. When the rigid pipe 14 moves downwards, the two sealing slide plates 17 move away from each other, and the rigid pipe 14 passes between the two sealing slide plates 17, extending into the rubber bottle 12.

[0029] The other features of Example 2 are the same as those of Example 1.

[0030] Example 3: Based on Example 2, additional technical means were added to facilitate the removal of the installation box 13 and the sealing slide plate 17.

[0031] Key reference Figure 3-5 This embodiment also includes a threaded rod 22, a baffle 27, and a rotating wheel 21.

[0032] The extension block 18 is detachably mounted on the sealing slide plate 17 by screws 19.

[0033] The fixed plate 23 has a threaded groove 25, and the first connecting plate 24 has a circular groove 26. The threaded rod 22 passes through the circular groove 26 and is threaded into the threaded groove 25. A baffle 27 is fixedly connected to the outer wall of the threaded rod 22. The baffle 27 presses against the outer wall of the first connecting plate 24. Side grooves 16 are provided on both sides of the mounting box 13. The two threaded rods 22 pass through the two side grooves 16 respectively, and the two threaded rods 22 are fixedly installed with a rotating wheel 21 at the part outside the mounting box 13.

[0034] The other features of Example 3 are the same as those of Example 2.

[0035] In practice, when it is necessary to weigh and fill the glue bottle 12, multiple glue bottles 12 are first placed inside multiple round sleeves 10. At this time, the bottom of the glue bottle 12 is pressed on the weighing sensor 11 and the weight of the glue bottle 12 is detected.

[0036] At this point, the innermost glue bottle 12 is positioned at the bottom of the rigid pipe 14. Activating the electric telescopic rod 3 causes it to retract, at which point the mounting base 29 moves the rigid pipe 14 downwards. The rigid pipe 14 then moves the hinge rod 20 and the extension block 18, causing the two sealing slide plates 17 to move away from each other, allowing the rigid pipe 14 to pass between the two sealing slide plates 17 and extend into the outermost glue bottle 12. Activating the electric valve 28 then allows the rigid pipe 14 to fill the glue bottle 12. The PLC controller compares the weight detected by the weighing sensor 11 at the bottom of the glue bottle 12 with a preset weight. When the weight detected by the weighing sensor 11 matches the preset weight, the PLC controller closes the electric valve 28. Extending the electric telescopic rod 3 then moves the mounting base 29 and the rigid pipe 14 upwards, bringing the rigid pipe 14 to the top of the glue bottle 12.

[0037] Then, the motor 7 is started and the adjacent glue bottle 12 is moved to the bottom of the rigid pipe 14, so that the rigid pipe 14 extends into the glue bottle 12 and opens the electric valve 28. At this time, the PLC controller detects the weight of the weighing sensor 11 at the bottom of the current glue bottle 12 and compares the data. When the weighing sensor 11 detects that the preset weight has been reached, the electric valve 28 is closed.

[0038] Repeat the above steps to weigh and fill each glue bottle 12 with a preset weight of electronic encapsulation adhesive.

[0039] When it is necessary to disassemble the mounting box 13, first insert the wrench into the screw 19 through the side groove 16 to separate the extension block 18 and the sealing slide plate 17, and then remove the two sealing slide plates 17. Then rotate the rotating wheel 21 to separate the first connecting plate 24 and the fixing plate 23, and then remove the mounting box 13 from the mounting back plate 1, so that the rigid pipe 14 and the fixing plate 23 move out from the first limiting slide groove 15, completing the disassembly of the mounting box 13.

[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
